I am trying to display a custom made slider with several images and files for my GIS elements.
Example URL: https://eudala2.getxo.eus/slidergetxo/?width=500&height=500&codtipoexp=LMO&codruta=islas&idelem=prueba
The problem comes when I add the website as Attached Control and Display it as Web View in the Integrated Document Viewer.
The slider is not loaded properly:
And it leaves a bunch of console errors pointing to no ES6 compatibility (async functions, etc.).
I tested it out in several versions including 3.34.
EDIT 10.04.2024: I opened issue in QGIS github: https://github.com/qgis/QGIS/issues/56820
HtmlWidget
and display your code there (and adjust it to display the selection). Try looking at the answers here
