How to auto tick multiple choice options when 'All the above" selected?

 Is it possible to automatically select all multiple choices with a tick if the choice "select all of the above" is selected

I believe that you are referring to the following field on the form.

It is possible to set a condition to auto select all the options in a multiple choice field. However, unfortunately, it is not possible to apply the condition for both as a rule and action set. You may have a separate field to display an option to select 'All the features' from the multiple choice field. 

You may add the options separated by commas in the condition. Please refer to the guide below that can help you with setting up a condition.

Since one of the options from the multiple choice is having commas, you may need replace them with a semi-colon or text.

Here is the cloned version of your JotForm added with a new field and condition.
