Select does not work when creating dynamic ranges

[quasaray]

I have a dynamic range, for selecting the start and end of an interval, which uses two select inputs for choosing the start and end.

Whenever the range changes though, the newly added values are not selectable. The values still display on the select, but clicking on them does not update the select value.
e.g if the start value has [1,2] but is then expanded to [1,2,3], 1 and 2 can be selected, but 3 cannot.

I have created a stackblitz reproducing the problem here, changing the end value to a larger number will update the display of the start values, but it can only select what was originally present.

Is the Select component not intended for dynamic menus? I could not see anything in the documentation about it.

There is a bug in inspectChildren.

The children introspection is a common pattern in ReactJS, but nonexistent in SolidJS. I don't know if this case can be fixed, otherwhise I would have to use contexts. I need to investigate further.

Also having this issue. Glad I finally found a post about it because I thought it was just me 😅

Same here - any workarounds?

native select still works fine, I am using that for now

It seems like this might also be an issue for buildless environments? Even when not using dynamic options. No onChange triggered. NativeSelect works fine as well, though less ideal as I also want to use the multi select chip component in this environment. and the Native version of multiselect doesn't seem to work correctly (I can't seem to get it working in a normal solid build either)

e.g.

  const [value, setValue] = createSignal(props.defaultValue);
  return html`
    <${Show} when=${props.visible}>
      <div class="py-4">
        <${InputLabel}>${props.name}${" "}<//>
        <${Select}
          title=${props.title}
          label=${props.name}
          name=${props.name}
          value=${value}
          disabled=${props.disabled}
          fullWidth=${() => props.fullWidth ?? true}
          onChange=${(e) => setValue(e.target.value)}
        >
          <${Show} when=${() => !props.required}>
            <${MenuItem} value="">
              <em>None</em>
            <//>
          <//>
          <${MenuItem} value="1">
            <em>Item 1</em>
          <//>
        <//>
      </div>
    <//>
  `;

Hi guys! I have created an SSR compatible version of the select component here. You can check it out, unfortunately it is not compatible with the Select API of MUI, but that is as close as I it gets, I guess, and I also support dynamic ranges with <For/> component

Same here - any workarounds?

My current workaround is the wrap the Select elements with <Show>, and hide / reshow them whenever the value list changes.

If I understand correctly, the whole problem is that in SolidJS it is impossible to get the properties of child elements - the DOM node is returned instead.

As another workaround, I suggest WeakMap with all MenuItem's. Why not?
Only what we need - find all .MuiMenuItem-root in the props.children and then convert to the props using WeakMap.

That's a good point, i haven't ever heard of that until now, but it seems to solve the technical issues i had. Unfortunately i currently don't have a lot of time, to implement this but I could offer to review the pr.

PR is here: #292

Temporary fix for me is use

Array.map and jsx interpolation

<Select>
  {names()?.map((name) => (
    <MenuItem value={name}>
      {name}
    </MenuItem>
  ))}
</Select>

instead of

<Select>
  <For each={names()}>
    {(name) => (
      <MenuItem value={name}>
        {name}
      </MenuItem>
    )}
  </For>
</Select>
