Add a component for selecting multiple items

[carolyncole]

Extract the component from tigerdata to allow a user to select multiple items from a list and put the selected items below. See this UI pattern from the tigerdata department selector

Acceptance criteria

• I can successfully use this feature with Voice Over in Safari.
• I have checked this feature using one of the following browser extensions and confirmed that it does not add any level A or level AA issues:
  • axe dev tools
  • Lighthouse
  • Wave
• I can either pass a list of values that the user can select from
• I can use ajax to change the list based on user input
• I create an element below the list for each item selected
• This item could be a slot so that we can have multiple options for what gets created
• It can have place holder text and the place holder text does not collide with the selected option
