+# MudBlazor.MudScrollbar
+A MudBlazor extension package that styles the scrollbars throughout the application.
+
+## Usage
+Use the MudScrollbar as a component:
+
+```
+<MudScrollbar />
+```
+
+It doesn't matter where you use the component. You can place it start, end or whatever else. It overrides the native scrollbar.
+
+## Selector
+MudScrollbar communicates with `Selector` parameter. If you set it null or empty, it means all scrollbars will affect in the application (while the razor page is loaded,
+so its better to place it in Layout page to use between pages).
+<br /><br />
+Selector both supports id and class selectors in CSS. So both usage is valid (be sure that id selector starts with "#" and class selector starts with "."):
+
+```
+<MudScrollbar Selector="#id1" />
+<div id="id1" />
+```
+
+```
+<MudScrollbar Selector=".id2" />
+<div class="id2" />
+```
+As you see, MudScrollbar affects all scrollbars which container's id or class match the selector.
+<br /><br />
+With `Selector` property, multiple custom scrollbars in a single page is supported.
+
+## Supported Browsers
+The parameters works with webkit based browsers like Edge, Chrome, Opera and Safari.
+<br /><br />
+Firefox has different scrollbar mechanism, so the parameters doesn't work for firefox. MudScrollbar has `FirefoxStyle` parameter to adding styles manually.
+
+## Example

+
+## How to set MudSelect and MudAutocomplete's scrollbar styles?
+You need to add class to `ListClass` parameter. It should like this:
+
+```
+<MudScrollbar Selector=".id1" />
+<MudSelect ListClass="id1" />
+```
