So im using one of the vertical portfolio pages. However my post is running too long, it has multiple topics under different subheadings and ive customized the layout using different picture and text widgets. I don't want the user to have to scroll all the way to the bottom and instead want to have a toggle option where they can either lengthen or minimize topics. There doesn't seem to be a way to do this with the toggle widget that exists - it has only a text option. Could you help me out?

Hmm im not familiar with shortcode. It gives some instruction on how do it it isolated, but not with widgets of other themes. It doesnt work as a drag and drop thing, it too works with code and text like your toggle feature.
