How to wrap text inside a Radio Button List Control.

Before You Begin

The Radio Button List Control does not wrap text by design.


As an alternative, you may use a Radio Button Group control to work around the behavior. Image

This requires at least the K2 Five 5.1 FP 10 to work as expected.

How-to Steps

  1. Navigate to ...\K2 smartforms Runtime\Styles\Themes\
  2. Make a backup of the theme in use (eg. Platinum.css)
  3. Open and edit the stylesheet to add the following snippet:
    .theme-entry .stack-container .stack div.multi-select-box-list-item label.input-control .input-control-text
       display: -webkit-box;
       vertical-align: top;
       white-space: normal;
       overflow: visible;
       text-overflow: ellipsis;
       max-width: calc(100% - 20px);
       margin: 0; float: none;
  4. Save and close the stylesheet that was modified
  5. Perform an IISRESET
  6. Clear the browser cache before reloading the view or form with the Radio Button List control.


Before applying a CU/FP or performing an upgrade, make a backup of the stylesheet as this process may overwrite the changes.
