Ext JS Ext.form.CheckboxGroup, select just one or none


This is just a small post with a tip how you can have in Ext JS (version 4.2 up to 6) an Ext.form.CheckboxGroup with the ability to select just one at the time, or none at all.

I needed this for a project I am working on and while I was searching on the internet I saw I wasn’t the only one looking for something like this. Therefor I shared it with you.

The Sencha Fiddle to try it for yourself you can find here: link
