I must create a wordpress plugin that allows you apply the google fonts. However I want the consumer to have the ability to select from all fonts available. To get this done I am unable to make use of a static xml manifest for that menu but I have to produce a up-to-date listing of the fonts instantly.

So how do i customize the wordpress plugin parameters programmatically? Could it be also easy to use javascript to include some behavior towards the menus for many ajax work?

Thanks

You have to produce a custom element and combine it with plugin's xml file.

This doc will show you how you can add custom element to some form.

You need to simply change it out based on you.

This doc is simply for instance, you need to to make use of exact this code, for instance do not need to to fret to save param. Joomla will instantly save the params of wordpress plugin.
