I'm trying to implement Mapbox on my website. I would like to add on my home page, an autocomplete field.
I know I can add it to the map, but I would like to know if I can use a separated input field to get the job done ? I've not found anything on the Mapbox documentation.
Can someone help me with this ?
Thanks.

The mapbox team has done a good job in showing an example of it in Geocoder
And regarding your query: Yes, you can use your own input field. What you have to do is listen for every keyboard input as shown in this. Take that value as the query parameter and then make the API request as done in search.js and then display the suggestions returned by the API.
If you are using React, then you could very well, use the same code and just modify the styles for your input.
For placement of the input box If you are using leafletjs, then you can add this input as a control else, if you are using mapbox-gl-js, then you can add it as its specific control. The Control API has only fixed positions such as top-right, top-left, bottom etc. If this is not your intended positioning, then you can just place it as a simple div overlay.
