Collapse `Advanced options` record on custom connector

Thanks for taking the time to respond and the pointers Anonymous .

The Essbase connector you cite does show some of the more advanced UX patterns I'd like to acheive but I don't think the source is available for this.

Of the samples only HelloWorld covers some basic documentation. It feels like there is posiibly an undocumented area of the SDK here.

There are a number of UI choices I see on other connectors which don't appear to be acheivable using the function documentation options I am aware of (Documentation. and Formatting. fields).

My connector is functioning as I want and I can surface any settings I need but it seems like I am missing something wrt to how to tweak what UI Power BI will show on adding a data source. To include some additional examples:

• (as per this post) I can't find the option which would cause the UX associated with the Advanced options record to resolve to a collapsed rather than expanded section by default.
• I can enable direct query via SupportsDirectQuery on the Publish record but the radio buttons associated with this always appear at the bottom of the dialog for me - whereas some connectors (e.g. Essbase ) indicate that this need not always be the case.
• So far I have not been able to get a field on a record parameter (e.g. an entry under Advanced options) to respect the formatting options (e.g. Formatting.IsMultiLine) whereas the Documentation. metadata is respected. Again I see this in other connectors (typically multiline SQL entry fields under advanced options) so it must be possible.
