ACSelect set element by index value

[Koxx3]

Hello,
currently, I set ACSelect element value by using a dirty if/else :

Did I miss something ?
Could it be possible to add a function to set the value from index ?

Getting the selected index is much easier and work fine ;)

Nota : yes, I have to use my own store/load function in a more larger settings environment (BLE, TFT/keys ...)

What does the index point to? Do you want to add a string as the nth-option that can be selected as a SELECT element?
That is, does that mean you want to control the order of selectable options string when they appear on a web page as HTML elements?
If so, you cannot. ACSelect has the values as std::vector<String>. That it to each element linearly, and stored while maintaining the order.

NOTE
This topic has converted to the discussions.

Let's take an example :

ACSelect(ACE_SETTINGS_Default_eco_mode_at_startup, {"Max","Medium","None"}, "Startup eco mode", 2);

I'd like to be able to do :

aux.setElementValueByIndex("ACE_SETTINGS_Default_eco_mode_at_startup", 1);

... to select element number 1, aka "Medium".

The substance of the element value of ACSelect is stored in the sequence container created by std::vector. Therefore, it cannot store the value by specifying an index that directly indexes the element value.
Also, the insertion of std::vector can be positioned using an iterator, but it is a relative position, not the absolute coordinates indicated by the so-called index.
(e.g. If the container has 1 elements currently and you try to insert it 3rd (as index), the result will be undefined. (which will probably cause a segfault)
Therefore, your requirement does not conform to the data structure of ACSelect.
