Crazy with drop down menu

Hello. Like other user im in trouble with using Element Click Selector to get sizes from a drop down menu. I have read other post, but even with that, i cant take a solution to my problem.

I need to scrape the available sizes of the next website products:

Really, im crazy with that. If any user could help me, i will be really grateful!

Thanks.

To get all the sizes in one line, your best bet is probably Type: Grouped:

Type: Grouped
Selector: div[class^='input-box'] > select[name] > option[value]:not([disabled]

You will need to do post-processing, but the Json patterns are consistent and unique, so you could just use Notepad or similar.
