Utilizing SubHeaders in Material UI Select Menu for Enhanced Organization

Question

Utilizing SubHeaders in Material UI Select Menu for Enhanced Organization

I'm facing a challenge in setting up a lengthy list of Menu Items on a Select control that incorporates sticky SubHeaders. The issue arises when the items scroll, as they end up obstructing the subheaders.

To tackle this problem, I examined the Material UI examples of grouped Select items as a reference point. My goal is to achieve a similar behavior to the Material UI example featuring pinned subHeader Lists.

You can find a working example on codeSandbox showcasing what I've been attempting.

Below is a snippet from my code:

<Select
        className={classes.root}
        MenuProps={{ className: classes.menu }}
        value="Pick one"
        onChange={e => {}}
      >
        {subHeaders.map(header => (
          <li key={header}>
            <ul>
              <ListSubheader>{header}</ListSubheader>
              {items.map(item => (
                <MenuItem key={item} value={item}>
                  {item}
                </MenuItem>
              ))}
            </ul>
          </li>
        ))}
      </Select>

Answer №1

Utilizing the Select component, we can replicate the desired behavior with some adjustments. However, it may not be suitable for your specific needs as the Select component does not support nested items within child elements, making it difficult to identify the selected element.

Alternatively, you can explore the functionalities of the Autocomplete component which may better cater to your requirements.

In reference to the provided example, there are possible solutions available, although maintaining the state of the selected item might pose a challenge. To align the behavior with the list, similar actions need to be applied to the menu that will be rendered by the Select component. Utilizing the prop MenuListProps, you can mimic the behavior from the list example.

I have made the necessary adjustments to your example.

I successfully implemented a solution using Material-ui select with sticky MenuItems.

Instead of using all the

<li>, <ul>, <ListSubheader>

, utilize MaterialUI MenuItem.

    const [isOpen, setIsOpen] = useState(false);
    const [value, setValue] = useState();
    
    const onToggle = () => {
        setIsOpen((prev) => !prev);
      };
    
    const onClose = () => {
        setIsOpen(false);
      };
    
    const _onChange = (event: React.ChangeEvent<{ value: unknown }>) => {
        const valueToSelect = event.target.value as Value;
        if (
          isResetSeletced(valueToSelect) ||
          (multiple
            ? !valueToSelect.length ||
              valueToSelect.length < minSelections ||
              (valueToSelect as string[]).some((option) => !option)
            : !valueToSelect?.length && minSelections > 0)
        ) {
          return;
        }
        event.persist();
        onChange(valueToSelect);
      };
    
      const renderValue = (selected: any) => {
        if (!selected.length) {
          return '';
        }
        if (multiple) {
          const isReachedLimit = selected.length > MAX_SELECTIONS;
          const hiddenTags = isReachedLimit ? (
            <span>+{value.length - MAX_SELECTIONS}</span>
          ) : null;
          const selectionsToShow = isReachedLimit
            ? selected.slice(0, MAX_SELECTIONS)
            : selected;
          return (
            <StyledTagsContainer>
              <Tags values={selectionsToShow} onRemoveTag={onRemoveTag} />
              {hiddenTags}
            </StyledTagsContainer>
          );
        }
        return selected;
      };


  const resetMenuItem = secondaryOptions?.map((resetItem, index) => {
    return (
      <MenuItem
        key={resetItem.value + index}
        onClick={() => {
          resetItem.onClick();
        }}
        isLast={!index}
        isSelected={
          resetItem.value === resetSelected?.value ||
          resetItem.value === value ||
          (multiple && resetItem.value === value[0])
        }
        value={resetItem.value}
        icon={<RadioIcon />}
      >
        {resetItem.text}
      </MenuItem>
    );
  });
    
    
    <Select
        displayEmpty
        onClose={onClose}
        value={value}
        onChange={_onChange}
        renderValue={renderValue}
        open={isOpen}
      >
        {menuItems}

        <div style={{ position: 'sticky', bottom: 0 }}>
          {resetMenuItem}
        </div>

I encountered a similar issue that required a specific solution to resolve. For optimal functionality, ensure that you have just one list structured in the following format:

[
  {
     value,
     text,
     isParent (is section)
  }
]

It is crucial for this list to be organized in the following order: Parent 1 - Child 1 (parent 1) - Child 2 (parent 1) - Parent 2 - Child 1 (parent 2)....

Subsequently:

const array = [
  { text: 'parent 1', isParent: true }, 
  { text: 'child 1 parent 1', value: 2, isParent: false }, 
  { text: 'child 2 parent 1', value: 3, isParent: false }, 
  { text: 'parent 2', isParent: true }, 
  { text: 'child 1 parent 2', value: 4, isParent: false }, 
  { text: 'child 2 parent 2', value: 5, isParent: false }, 
]

<Select>
  {array.map(option => {
    if(option.isParent)
      return (
        <ListSubheader>
          {option.text}
        </ListSubheader>
      )
    else
      return (
        <MenuItem 
          value={option.value}
        >
          {option.text}
        </MenuItem>
      )
  })}
</Select>
