I’m trying to create a data table widget with a column in each row being clickable, which then expands into a subtable.
I’ve tried to glean how to do it from looking at the code for the Search Terms widget, but can’t decipher how it’s done.
I can’t find anything in the documentation either, that explains how to create these kinds of widgets.
Can anyone explain how I can do this please i.e. how to tell Piwik which column should link to the subtable and that the subtable should be expanded when a row in that column is clicked?
