I want to create a scrolling item menu similar to the bottom row shown here:
I need to mask (clip) the extents of the menu from being visible (a gradient is used here, but worst case the clipping could be a hard edge). Looking through forum posts, the only way I've seen this done is by using a Source-In blend mode effect on the item/s to be masked. As a test, I was able to create this by applying the effect to a text object and it works.
However, I want to build the menu using a set of buttons but apparently effects can't be applied to buttons or families. If I apply the Source-In effect to an entire layer, all layers beneath don't get rendered (or at least everything turns black).
How can I build the above menu using buttons and clip the visible width of the menu to the dimension I need?
Thanks in advance.
