If you are looking for a way to show items, and ask respondents to allocate chips to those items, then I suggest a CBC trick.

Use CBC, Advanced Design Module.  Put all the items as levels within the first attribute.  Then, add a second (dummy attribute, that you will end up ignoring) with at least two levels (use HTML's blank characters " " or blank graphics, that will not be visible to the respondents.

During utility estimation, tell CBC/HB or Latent Class to ignore ("exclude") utility estimation for the 2nd attribute.
