Dropdown list in a dhtml readeble by search engines

Hello,
I have a english website with other languages version.
Please let me know if i can creat classic select dropdown list in a dhtml and search engines to read (crowl) links from dropdown lists.

For example:

Blockquote
< option value=“https://www.qtransform.com/en/convert/volume.php” >english
< option value=“https://www.qtransform.com/ro/transforma/volum.php”>romana

How to transform it and Google, Bing and other to access and crowl links (urls) from … ?

Hello.

Please, try to use the dhx.Combo component:
https://docs.dhtmlx.com/suite/combo__index.html
It allows to display any needed html content in the options list:

and execute the needed JS code from the onChange event after selecting the needed option
