I've a requirement where I need to build a wizard and allow users to select one or more account entity records (on first screen) and products entity records (on second screen) from a tree view structure as the data in these entities are in hierarchical structure. Please know, these entity records are already present in Dynamics 365 CE/CRM.
On third screen, I would like to provide a sub-grid control with 20 or more than 20 columns wherein I wish to freeze the first 2 columns.
I'm planning to build this wizard in Power Apps and then load the same as web resource in Dynamics 365 CE V9.
Does any one have any ideas whether Power Apps has such in build controls, which could be used for this purpose?
For wizard, you could use multiple screens for navigation using navigate function. Use Gallery control to show all the entity records, and then use Display Form control to show the detail of specific selected record.
