I am new to Glide so forgive me, but why are many features which are available while building a mobile app, not available for web apps? Calendars, progress bars, and other components are not available for web apps. It seems that the web app development on Glide is incomplete. Are these features still under development by Glide?
Here is a pretty simple workaround until Glide has a Gallery feature for pages IF your images can be uploaded once and don’t require changing
Use Elfsight, a no-code widget maker to create a slider with a URL that can be shown in a WebEmbed element in pages. Elfsight has a lot of customization options that make it nice to use. You will need to upload the images to Elfsight so this is not a dynamic solution, so may or may not work for your specific project.
To make this, you need to create the widget in Elfsight, then grab the widget installation code, then add to a sandbox template url https://sandbox.elfsightcdn.com/WIDGET_ID and then use that link as the WebEmbed link.
Playing around with a thought to make it easier to add images - using a social feed widget instead to show only photos from a specific twitter feed. The idea would be to create a twitter account just for image upload and then display all images uploaded to that account. Still not the real solution we need - to upload images directly in Glide pages, but a workaround that is a little more dynamic. You can see sample of this on the demo now for @glideapps twitter feed.
