Hi Steve,

first of all, thanks for your great application!

Background:
Right now, I’m working on a slightly elaborated library system with Xataface and I could find nearly everthing in the Wiki or Forum, but now I could need some help:
I’ve got a table with publications (the main table), and beside some others, a table with categories and a table with catchphrases, they look like

[publications]
id … catchphrase_id

[categories]
id name

[catchphrases]
id name category_id

Problem:
I’ve got 690 catchphrases sorted in 16 categories and i would like to group them. Means, if I create a new record, I would like to
1st: select one or more categories
2nd: select one or more catchphrases from these categories.

Could you give me a hint on how i could achieve this?

Thank you very much & best regards
Axel

You’ll need to do something with Javascript here.
First, if you add a third column to the select of the catchphrases valuelist __sql__ query, where this third column identifies which category the catchphrase is associated with, then you’ll see that this value is added as a CSS class to the checkbox corresponding to that catchphrase.
Then you can use javascript to show or hide catchphrase checkboxes depending on which categories are selected. Wrap this in a javascript function and add it to both the document’s ready event and the change event of the category checkboxes.

Hi Steve,

thanks to your reply.

I’m not too familiar with Javascript, so could you help me with this (on account)?

Best regards
