Follow these simple steps to use EO.Web Floater control:

1. Drag a Floater control from the toolbox to your Web Form. See here if you can not find the control in your toolbox;
2. Place a blank HTML element (for example, a DIV element) in your page at where you would like the Floater control to be initially positioned and give the element an ID. For example:

   <!-- Other page contents -->
   <p>something....</p>
   
   <!-- Anchor element for the floater. The floater would
   appear at the same place as this div -->
   <div id="div1"></div>
   

3. Set the Floater control's TopAnchorID and LeftAnchorID to the ID of the anchor element, in this case "div1";
4. Place contents you would like to float inside the Floater control;
5. Run the page and you should see the Floater initially aligns to the anchor element. Scroll the page and you should see the Floater's position stay fixed;
