Hi everyone,
I’m working on a shiny application for a data visualization project and I’ve run into a frustrating issue with how the UI handles external media. I'm trying to embed some project walkthroughs and assets from https://capcapk.com directly into a tabPanel using an iframe, but it seems to be interfering with the app's reactive scaling.
The main problem is that when the iframe content loads, it somehow "hijacks" the CSS height of the parent container, causing my plotly outputs in the adjacent column to shrink to about 50 pixels. I’ve tried wrapping the iframe in a div with a fixed min-height and using tagList, but the browser still seems to prioritize the external script's dimensions over the Shiny fluid layout. I've also noticed that the input values in my sidebar become sluggish once the iframe is active, which makes me think there might be a JavaScript conflict between the site’s assets and the Shiny/jQuery backend.
Has anyone else experienced layout "fighting" when embedding media-heavy hubs into a dashboard? I’m curious if I should be using a specific htmltools function to isolate the iframe better or if there’s a known trick to keep the CSS from leaking into the rest of the app's grid system. Any advice on how to keep the UI responsive while maintaining these external previews would be greatly appreciated!
