What is use of ui:scrollerWrapper in Salesforce?

Hi Shradha,

A ui:scrollerWrapper creates a container that enables native scrolling in the Salesforce app. This component enables you to nest more than one scroller inside the container. Use the class attribute to define the height and width of the container. To enable scrolling, specify a height that's smaller than its content.
This example creates a scrollable area with a height of 300px.

<aura:component>
<ui:scrollerWrapper class="scrollerSize">
<!--Scrollable content here -->
</ui:scrollerWrapper>
</aura:component>

/** CSS **/
.THIS.scrollerSize {
height: 300px;
}

Here’s an example of how you might use ui:scrollerWrapper to make a tab’s content scrollable using the lightning namespace:

<aura:component>

<lightning:tabset>

<lightning:tab label="Item One">

<ui:scrollerWrapper> <div> Tab Content Goes Here </div>

</ui:scrollerWrapper>

</lightning:tab>

<lightning:tab label="Item Two"> Sample Content Two </lightning:tab>

</lightning:tabset>

</aura:component>

Thanks
