Hi,

We've been researching to create custom control add ins. However, during research, we found something that limit many the control add ins features and visibility.

First is the iframe and html body that hosts the control add in is by default hiding the scroll both horizontally and vertically. Please add a config in the control add in to specify whether the scroll will be shown or not. 

For iframe, the config should translate "scrolling" attribute to "yes" or "no" AND for the body, the config should translate "overflow" attribute to "hidden" or "scroll", they should be based on the config. 

The solution is: maybe inside the control add ins can be added something like this

controladdin DemoControl

{

  AllowScroll = true;

}

Second, the default placement of script inside control add ins is always before the body. Due to how some Javascript library works, sometime it's necessary to put the script tag AFTER the body because some of those library manipulate the document.body. document.body will be null if the scripts are runs before the body itself.

The solution is: maybe inside the control add ins, script can be configured to a something like this

controladdin DemoControl

{

  Scripts = { placement: 'before', 'script1.js' }

      , { placement: 'after', 'script2.js' }

}

Hopefully those two features can be implemented someday.

Thank you for the attention.
