Hi,

I have some problem with filling Select Element after rendering.

When I store data get from a layer'field into an array and I want to fill in the Select element with array's item.

but in widget life cycle there is not any place between render and destroy that I put my code:

this.layerList.map((item) => {

const opt = document.createElement("option");

opt.value = item;

opt.innerHTML = item;

const selectElement = document.getElementById("modeSelect");

selectElement .appendChild(opt);

})

I am not sure but I think in react's life cycle there is componentDidMount that do this job, I am looking

to find something like this in widget lifecycle.

I also tried to fill in Select element during rendering but I encounter with a error that means

Select element is not ready so I decided to find a way to do that after rendering.
