React-select wrong focus

[kaloyantihomirov]

I have the following react-select select component:

     <Select
          className={styles.multiselect}
          components={{
            Option: OptionBlock,
          }}
          isMulti
          closeMenuOnSelect={false}
          hideSelectedOptions={false}
          onChange={handleChange}
          value={selectedOptions}
          blurInputOnSelect={false}
          onMenuOpen={() => setIsOpen(true)}
          onMenuClose={() => setIsOpen(false)}
          placeholder="Select one or more topics of interest"
          options={options}
          styles={multiselectStyles}
        />

and here's my custom option component:

import { components, type OptionProps } from 'react-select';
  import type { ColorOption } from '../data/color-option';
  
  export function OptionBlock({ children, ...props }: OptionProps<ColorOption, true>) {
    const { isSelected, isMulti, data } = props;
  
    return (
      <components.Option {...props}>
        {isMulti ? (
          <>
            <input type="checkbox" checked={isSelected} value={data.value} onChange={() => {}} />
            <label>{data.label}</label>
          </>
        ) : (
          children
        )}
      </components.Option>
    );
  }

I have two questions and would really appreciate it if someone could nudge me in the right direction.

The first problem is that when I open the select dropdown, the focus is on the last option that is visible in the current scroll context. I want the focus to be on the first option by default. By playing with it, I am also left with the impression that the focus is put on a random option, when selecting different ones, so I am not really sure I understand what's going on.

I am also not sure I understand why I need the blurInputOnSelect={false} when I already have closeMenuOnSelect={false}, but if I don't have it, the menu closes on every option selection.

The version I am using is 5.10.1 so all issues I found opened on github should already be fixed in that version.

Any help would be appreciated.
