Joined: Mar 24, Posts: I know this is the default setting for dropdowns to always have an option active, but can I tell a dropdown to select nothing, and so having none of its items active? I've made some researches about that, and I found two solutions : - The first one : Setting the dropdown value to -1 by default. This solution works, but only once, and you need to change the value manually through the Inspector.
I've already tried resetting the value to 0 via script, but either my dropdown automatically sets "0" and so loads the first option without my word to say, OR prevents my script from finishing its execution. Well, it obviously finishes its execution, but it doesn't go through all my functions The second one : Creating a temporary option with 0 as value, then immediately removing it so that the dropdown cannot find it, and its selection remains blank.
This doesn't work. So, i'm out of options. I'm interested in any ideas you could come up with, provided that they're not too complicated After 3 years, I'm not really a beginner anymore, but I'm not a competent developer either yet. Thanks for your answer.

I just would like to get my options only, but with none of them selected, so that I can select the very first item in the list and still trigger the OnValueChanged event.

The deactivation overrides the activeSelf setting on all child GameObjects, so Unity makes the whole hierarchy inactive from the parent down. This does not change the value of the activeSelf property on the child GameObjects, so they return to their original state when you re-activate the parent. Instead, you should use the activeInHierarchy property, which takes the overriding effect of the parent into account.
