dijit.layout.TabContainer - additional examples

Tab Strip

This is a plain TabContainer with three tabs, fixed height and a tab strip. The tabstrip is especially useful when the TabContainer is child of a BorderContainer.

dojo.require("dijit.layout.TabContainer");
dojo.require("dijit.layout.ContentPane");

The HTML is very simple

<div data-dojo-type="dijit.layout.TabContainer" style="width: 400px; height: 100px;" tabStrip="true">
  <div data-dojo-type="dijit.layout.ContentPane" title="My first tab" selected="true">
    Lorem ipsum and all around...
  </div>
  <div data-dojo-type="dijit.layout.ContentPane" title="My second tab">
    Lorem ipsum and all around - second...
  </div>
  <div data-dojo-type="dijit.layout.ContentPane" title="My last tab">
    Lorem ipsum and all around - last...
  </div>
</div>

The doLayout attribute currently only works for top tabs, left/bottom/right tabs don’t support it. You can set a tab strip on every tab type though. The following examples show left/bottom/right tabs, some using tabstrips.

Right Tabs

Tabs at the right, no strip. Note that right tabs don’t work in conjunction with doLayout=false.

dojo.require("dijit.layout.TabContainer");
dojo.require("dijit.layout.ContentPane");

notice the tabPosition attribute

<div data-dojo-type="dijit.layout.TabContainer" style="width: 400px; height: 100px;" tabPosition="right-h">
  <div data-dojo-type="dijit.layout.ContentPane" title="My first tab" selected="true">
    Lorem ipsum and all around...
  </div>
  <div data-dojo-type="dijit.layout.ContentPane" title="My second tab">
    Lorem ipsum and all around - second...
  </div>
  <div data-dojo-type="dijit.layout.ContentPane" title="My last tab">
    Lorem ipsum and all around - last...
  </div>
</div>

Left Tabs

Tabs at the left, with a strip. Note that left tabs don’t work in conjunction with doLayout=false.

dojo.require("dijit.layout.TabContainer");
dojo.require("dijit.layout.ContentPane");

notice the tabPosition attribute

<div data-dojo-type="dijit.layout.TabContainer" style="width: 400px; height: 100px;" tabPosition="left-h" tabStrip="true">
  <div data-dojo-type="dijit.layout.ContentPane" title="My first tab" selected="true">
    Lorem ipsum and all around...
  </div>
  <div data-dojo-type="dijit.layout.ContentPane" title="My second tab">
    Lorem ipsum and all around - second...
  </div>
  <div data-dojo-type="dijit.layout.ContentPane" title="My last tab">
    Lorem ipsum and all around - last...
  </div>
</div>

Bottom Tabs

Tabs at the bottom, with a strip. Note that bottom tabs don’t work in conjunction with doLayout=false.

dojo.require("dijit.layout.TabContainer");
dojo.require("dijit.layout.ContentPane");

notice the tabPosition attribute

<div data-dojo-type="dijit.layout.TabContainer" style="width: 400px; height: 100px;" tabPosition="bottom" tabStrip="true">
  <div data-dojo-type="dijit.layout.ContentPane" title="My first tab" selected="true">
    Lorem ipsum and all around...
  </div>
  <div data-dojo-type="dijit.layout.ContentPane" title="My second tab">
    Lorem ipsum and all around - second...
  </div>
  <div data-dojo-type="dijit.layout.ContentPane" title="My last tab">
    Lorem ipsum and all around - last...
  </div>
</div>

One technique to allow validation, and still use the parser would be to simply decorate the node with a data-dojo-type attribute (after onLoad) and parse the parent node. For ease, we’ll store the class name for our inner widgets in a rel=”” attribute.

dojo.require("dijit.layout.TabContainer");
dojo.require("dijit.layout.ContentPane");
dojo.require("dojo.parser");
dojo.ready(function(){
    dojo.query("div[rel]").forEach(function(n){
        var className = dojo.attr(n, "rel");
        // now set it
        dojo.attr(n, "data-dojo-type", className);
    });
    dojo.parser.parse("progtabwrapper");
});

<div id="progtabwrapper">
<div rel="dijit.layout.TabContainer" style="width: 400px; height: 100px;">
  <div rel="dijit.layout.ContentPane" title="My first tab">
    Lorem ipsum and all around...
  </div>
  <div rel="dijit.layout.ContentPane" title="My second tab">
    Lorem ipsum and all around - second...
  </div>
  <div rel="dijit.layout.ContentPane" title="My last tab">
    Lorem ipsum and all around - last...
  </div>
</div>
</div>

Programmatic Example

Here’s an example that parses existing DOM and creates tabs, similar to what the parser does:

As a simple example, we’ll use dojo.query to find and create the ContentPanes used in the TabContainer

dojo.require("dijit.layout.TabContainer");
dojo.require("dijit.layout.ContentPane");
dojo.ready(function(){
    dojo.query(".tc1cp").forEach(function(n){
        new dijit.layout.ContentPane({
            // just pass a title: attribute, this, we're stealing from the node
            title: dojo.attr(n, "title")
        }, n);
    });
    var tc = new dijit.layout.TabContainer({
        style: dojo.attr("tc1-prog", "style")
    }, "tc1-prog");
    tc.startup();
});

The HTML is very simple

<div id="tc1-prog" style="width: 400px; height: 100px;">
  <div class="tc1cp" title="My first tab">
    Lorem ipsum and all around...
  </div>
  <div class="tc1cp" title="My second tab">
    Lorem ipsum and all around - second...
  </div>
  <div class="tc1cp" title="My last tab">
    Lorem ipsum and all around - last...
  </div>
</div>

Nested tabs

Often sites will have two levels of tabs. This is supported by using two TabContainer widgets. Remember that although a TabContainer’s children are often ContentPanes, they can be any layout widget, including another TabContainer:

dojo.require("dijit.layout.TabContainer");
dojo.require("dijit.layout.ContentPane");

The HTML is very simple

<div data-dojo-type="dijit.layout.TabContainer" style="width: 400px; height: 100px;">
  <div data-dojo-type="dijit.layout.TabContainer" title="Tab 1" nested="true">
    <div data-dojo-type="dijit.layout.ContentPane" title="My first inner tab" selected="true">
      Lorem ipsum and all around...
    </div>
    <div data-dojo-type="dijit.layout.ContentPane" title="My second inner tab">
      Lorem ipsum and all around - second...
    </div>
    <div data-dojo-type="dijit.layout.ContentPane" title="My last inner tab">
      Lorem ipsum and all around - last...
    </div>
  </div>
  <div data-dojo-type="dijit.layout.TabContainer" title="Tab 2" nested="true">
    <div data-dojo-type="dijit.layout.ContentPane" title="My first inner tab" selected="true">
      Lorem ipsum and all around...
    </div>
    <div data-dojo-type="dijit.layout.ContentPane" title="My second inner tab">
      Lorem ipsum and all around - second...
    </div>
    <div data-dojo-type="dijit.layout.ContentPane" title="My last inner tab">
      Lorem ipsum and all around - last...
    </div>
  </div>
</div>

When you have nested tabs you should set the nested parameter to true, to make the formatting distinctive from the outer TabContainer.

Programmatic Nested tabs

This an example of nested tabs created programmatically. If there is no nested tab in a tab, content pane is inserted instead.

dojo.require("dijit.layout.TabContainer");
dojo.require("dijit.layout.ContentPane");
dojo.ready(function(){
    var tabs = [{
        title: 'Tab 1',
        sub: [{
            title: 'My 1st inner',
            content: 'Lorem ipsum dolor sit amet'
        }, {
            title: 'My 2nd inner',
            content: 'Consectetur adipiscing elit'
        }]
    }, {
        title: 'Tab 2',
        sub: [{
            title: 'My 3rd inner',
            content: 'Vivamus orci massa rhoncus a lacinia'
        }, {
            title: 'My 4th inner',
            content: 'Fusce sed orci magna, vitae aliquet quam'
        }]
    }, {
        title: 'Tab 3',
        sub: []
    }];
    var tabContainer = new dijit.layout.TabContainer({
        doLayout: false
    }, 'tabContainer');
    dojo.forEach(tabs, function(tab){
        if(!tab.sub.length){
            var cp = new dijit.layout.ContentPane({
                title: tab.title,
                content: 'No sub tabs'
            });
            tabContainer.addChild(cp);
            return;
        }
        var subTab = new dijit.layout.TabContainer({
            title: tab.title,
            doLayout: false,
            nested: true
        });
        dojo.forEach(tab.sub, function(sub){
            var cp = new dijit.layout.ContentPane({
                title: sub.title,
                content: sub.content
            });
            subTab.addChild(cp);
        });
        tabContainer.addChild(subTab);
    });
    // _Container widgets will call startup on their children already
    tabContainer.startup();
});

<div id='tabContainer'> </div>
