Thanks for this, works beatifully.
While checking it out, I found that we need to fix a couple of more things:

• The mobile "affix" button:

• The index page, which still show the standard button for voting that does not work, should be like:

This is improving!

• see that some views still look not good, specially in the grid for some same-small screens

One solution we could apply is to remove the flex-direction: column from the .vote-block, the it looks much nicer:

• The "loading" status does not appear in the list

• Also, the instructions box does not appear

couldn't be this part the vote_block_for ?

I've applied som css corrections.

I've found that in the list view, no title in the modal is shown.

Other things to consider:

• The Readme file mentions the metadata cell, needs to be updated
• In this PR, the modal in the list is created as many times as the items in the list. Can we just add one modal and update the content?
• The VotingCardsProposalCell is too complicated, can we create two cells that inheritht one from the other? let's render one or the other depending on if it is comming from a list or not.
• There is a problem when you vote on the list, it renders the cell inside the class voting-voting_cards when updates the cell, leading to css mistmaches: I think this happens because the file _show_vote_button.html.erb

[microstudi]

can we find the voting container here and add the "loading" class too?

[microstudi]

let's add this to the checksum.yml
