I know It sounds "funny", but that is the client requirement, so... What I've done created the js for showing and hiding the columns width(numberfields) and a validation.js in order to only able the editor to submit the dialog if the total width is <= 100, that was done by using a clientlibrary with categories[cq.authoring.dialog] . So I used the use api to retreive that data and put a styles variable in a input type="hidden", after that I created a js in a secondary clientlibrary destinated to the clientSide and in that js I created the css classes dynamically. My requirement is done.
Still... I would like to know how could I change the max attribute of a numberfield, I was trying to do that, but I was not able to know what I should change in the granite numberField that I was getting with jquery selecting a class that I had assigned to each numberfield. Anyway, I already made the component, but I would like to know if you guys have ever made something like that and if yes let me know how, thanks.
