Tabs
The TabStrip provides advanced options for configuring its tabs.
Tabs Positioning
The TabStrip API provides the TabPosition configuration option that allows you to set the position of the tabs. You can position the tabs to the top, left, right or bottom of the TabStrip via the TabStripTabPosition
The following example demonstrates how to position the TabStrip tabs to the right:
@(Html.Kendo().TabStrip()
.Name("tabstrip")
.TabPosition(TabStripTabPosition.Right)
.Items(items =>
{
items.Add().Text("One")
.Content(@<text>
<p>Tab One</p>
</text>);
items.Add().Text("Two")
.Content(@<text>
<p>Tab Two</p>
</text>);
items.Add().Text("Three")
.Content(@<text>
<p>Tab Three</p>
</text>);
})
)
Dynamic Tabs
The TabStrip API provides methods for dynamically adding or removing TabStrip bars.
- Get a reference to the TabStrip widget in JavaScript.
- Provide the new item as a JSON object along with a reference item. A reference item is a target HTML
tabelement that already exists in the TabStrip. The reference item will be used to determine the exact position of the new tab. To get a reference to the target item, you can use any valid jQuery selector.
The following example demonstrates how to add a new TabStrip tab and position it after the first existing tab.
@(Html.Kendo().TabStrip()
.Name("tabstrip")
.Items(tabstrip =>
{
tabstrip.Add().Text("Paris")
.Content(@<text>
<p>Rainy weather in Paris.</p>
</text>);
tabstrip.Add().Text("Sofia").Selected(true)
.Content(@<text>
<p>Sunny weather in Sofia.</p>
</text>);
})
)
<script>
var tabstrip = $("#tabstrip").data("kendoTabStrip");
tabstrip.insertAfter(
{
text: 'Sydney',
content: '<p>Rainy weather in Sidney.</p>'
},
tabstrip.tabGroup.children("li:first")
);
</script>
Scrollable Tabs
The TabStrip supports scrollable top and bottom tabs through TabPosition(). During initialization, the TabStrip checks if the tabs fit in the available horizontal space and if not, renders scroll buttons on the sides. By default, the scrollable tabs are enabled. To disable them, use the Scrollable(false) method of the Kendo UI for jQuery widget.
If the TabStrip has no fixed width and is placed in a fluid layout, it can re-check whether tab scrolling is necessary or no longer required. To enable this option, execute the resize() method of the Kendo UI TabStrip for jQuery upon window.resize. The resize method will also render the right scroll button if the last and selected tab becomes invisible as a result of TabStrip shrinking.
<div style="width: 150px;">
@(Html.Kendo().TabStrip()
.Name("tabstrip")
.Scrollable(false)
.Items(tabstrip =>
{
tabstrip.Add().Text("Paris").Selected(true)
.Content(@<text>
<p>Rainy weather in Paris.</p>
</text>);
tabstrip.Add().Text("Sofia")
.Content(@<text>
<p>Sunny weather in Sofia.</p>
</text>);
})
)
</div>
Sortable Tabs
You can sort the TabStrip tabs by dragging and dropping the tabs into the desired position. To enable this feature, set the Sortable() option to true.
The following example demonstrates how to enable sortable functionality, which is disabled by default.
@(Html.Kendo().TabStrip()
.Name("tabstrip")
.Sortable(true)
.Items(tabstrip =>
{
tabstrip.Add().Text("Paris")
.Content(@<text>
<p>Rainy weather in Paris.</p>
</text>);
tabstrip.Add().Text("Sofia")
.Content(@<text>
<p>Sunny weather in Sofia.</p>
</text>);
})
)
Tabs Appearance
You can add HTML code into the item's Text() method to customize the appearance of the tab. Disable the Encoded() option to ensure that the HTML will render correctly.
The following example showcases how to add a button element inside a specified tab of the TabStrip.
@(Html.Kendo().TabStrip()
.Name("tabstrip")
.Items(tabstrip =>
{
tabstrip.Add()
.Text("<button id='tab1Btn' class='k-button k-button-md k-rounded-md k-button-solid k-button-solid-base k-icon-button' type='button' onclick='tabBtnClick();'>Read more</button>")
.Encoded(false)
.Selected(true)
.Content(@<text>
<p>Rainy weather in Paris.</p>
</text>);
tabstrip.Add().Text("Sofia")
.Content(@<text>
<p>Sunny weather in Sofia.</p>
</text>);
})
)
<script>
function tabBtnClick() {
// Handle the button 'click' event.
}
</script>
Selecting Tab on Initial Load
You can select a tab and display its associated content upon the initial load of the TabStrip.
To select a tab on initial load, apply either of the following approaches:
- Use the
Selected()configuration option on the required tab. - Use the
SelectedIndex()configuration method on the TabStrip HTML helper.
The following example demonstrates how to use the Selected() configuration method.
@(Html.Kendo().TabStrip()
.Name("tabstrip")
.Items(tabstrip =>
{
tabstrip.Add().Text("Paris")
.Content(@<text>
<p>Rainy weather in Paris.</p>
</text>);
tabstrip.Add().Text("Sofia").Selected(true)
.Content(@<text>
<p>Sunny weather in Sofia.</p>
</text>);
})
)
