I have read all of the articles and support threads below, but I am still confused and have many questions:
1. Are themes required to use Layouts or can I use another 3rd party theme (e.g. Astra)?
2. Are users of the theme required to purchase a Toolset license of their own?
3. How much Toolset functionality does a theme user have (e.g. can users edit views and content templates)?
Below document is what you needed:
How to build Toolset-based themes
This is the technical support forum for Toolset - a suite of plugins for developing WordPress sites without writing PHP.
Everyone can read this forum, but only Toolset clients can post in it. Toolset support works 6 days per week, 19 hours per day.
