Is it possible to prevent the dropdown to open in the ComboBox?

[Ewald]

I have a ComboBox, and when the user opens it, I first want to execute some code that takes a while. Only when that code is completed, I want to open the dropdown. Is this possible?

Hello, Ewald,

Yes this is possible by handling the opened state of the ComboBox component in controlled mode.

In the below example, I am setting the opened prop to the `open` state variable. In the onOpen event handler, I am setting the `open` variable to true. Before that, you can execute the needed code and if necessary set the `open` variable in a `setTimeout` method:

I hope this helps, but please let me know if you have any further questions.
