I'm working on a custom character sheet. I want to create a little mini-database of feats and spells. Each feat or spell will have multiple attributes which can be searched for. (eg: Themes, Relevant Attributes, and Mechanics-Categories) For example: <div class="sheet-feat" data-skins="nature, alchemy" data-attributes="intellect, empathy" data-categories="control, root"> <div class="sheet-featName">Grasping Tendrils</div> <div class="sheet-featDesc">Reach out and hold anyone withing 3 squares radius.</div> </div> I have a working jsfiddle, but I can't get it to work in Roll20. It seems like roll20 strips out my data- attributes in the html. <a href="https://jsfiddle.net/L035dLsz/3/" rel="nofollow">https://jsfiddle.net/L035dLsz/3/</a> Anyone know what I'm doing wrong?
