How to custom combobox header template

[skillcrushbinguyen]

Hi FluentUI Community,
I would like to implement a similar UI below in combobox, could you please share some ideas to implement it in FluentUI? Thank you!

You should probably use a FluentTextField and a FluentAnchoredRegion. We've used these components to create the FluentAutocomplete component. You can find the implementation here, for inspiration :-)

Unfortunately, inherit from ListComponentBase is impossible because InternalListContext is internal scope :D
Do you have any suggest for me? Thank you!

I don't think this is possible to do with FluentComboBox. It uses and renders the fluent-combobox web component internally so that will always be used. If you want this component, I'm afraid there is nothing other to do than to build it yourself. You can, of course, use our TextField, Button and Listbox to display the UI but the logic will need to be built. For that you can use the ListComponentBase and InternalListContext and any other part of our code as inspiration.

If it all works out and you have a nice component, you can perhaps propose to add it to the fluentui--blazor-community repo.
