Hi Andrew,
Thanks for reaching out and thanks for using BoldGrid Post and Page Builder for WordPress!
While we don’t have a scrollable timeline block I do think it’s possible to use one of our pre-designed block elements and adjust it to display as a scrollable timeline. You can search through the auto-generated blocks inside of the post and page builder by clicking the blue “Add Block” button towards the top of your page editor.
If you do find a block that works for you and you need help adjusting it feel free to switch to the “text” editor tab and copy/paste the contents directly into this thread and we’d be happy to help you modify it to display the way you want.
As far as hosting your PDF files using a third party platform like Dropbox might be a solution to look into. That way you maintain full control of your folders and still have the ability to share them with your users and link to the files in your content.
Creating manageable folders from your dashboard can be accomplished using a plugin like WP Folders. This plugin will allow you to easily organize content in folders directly from your WordPress dashboard.
I hope this helps Andrew. Please reach back out if you have any other questions for us.
