I have tried setting up multiple galleries in a single page (article). The method I used was to create a 3 column, multi-row TABLE in the TinyMCE editor and (as suggested by Yiota) use single thumbnail mode in the gallery code. This method works fine.
One problem I have, though, is I would like the resulting 'grid' of images to be RESPONSIVE. The template I am using is itself 'responsive', but the table I am using to 'hold' the 'gallery menu' images is NOT responsive. Can anyone suggest how this might be done? Is there a 'responsive table' plug-in to use in the editor, for example. Or is there some custom CSS code that I can somehow use to get a responsive table?
What I mean by 'responsive' behaviour is that when the window is made narrower, the number of columns (of thumbnails) reduces from (say) 3 to 2 to 1. Probably on a phone screen, there would only be room to fit a single column of thumbnail images, for example.
I would be grateful for any help that anyone could offer on this question.
