Blazor Splitter Overview
The Blazor Splitter component lets you divide a portion of the page into several pieces that the user can resize and collapse. This provides real estate management for the app and the end user so they can focus on the content that is important in their current task. You can also save and load its state, and respond to events.
The Splitter component is part of Telerik UI for Blazor, a
professional grade UI library with 100+ native components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.

This example shows how the splitter can fill up the entire container (marked with a red border) and the main features of the component and its panes.
<div style="width: 500px; height: 300px; border: 1px solid red;">
<TelerikSplitter Width="100%" Height="100%" Orientation="@SplitterOrientation.Horizontal">
<SplitterPanes>
<SplitterPane Size="100px" Min="50px" Max="150px" Collapsible="true">
<div>left sidebar. Can be collapsed and can be resized between 50px and 150px.</div>
</SplitterPane>
<SplitterPane Collapsible="false">

<div>Third pane that is initially collapsed and is not resizable.</div>
</SplitterPane>
</SplitterPanes>
