Submit button with multiline value in rails & haml

For some cases, I'd like to have multiple lines in 'Submit' button value. I'm using Rails 6 and haml.

This is what I've came up with (don't work):

form_view.html.haml:

- if @count < 0
  - check_btn_val = "Submit"
- else
  - check_btn_val = "Submit<br>You have " + @count + " submissions remaining"
%input{"type" => "submit", "value" => check_btn_val, ...}

<br> is ignored and treated as plain text (button label contains "<br>" indside the value).

I've seen this question HTML: can I display button text in multiple lines? but I don't think this works for me, as it splits line based on fixed width of the button and my goal is to have break in specific place.

Here's how I fixed it for my case:

- addtnl_txt = ""
- if @count >= 0
  addtnl_txt = "You have $#{@count} submissions remaining"
%button{"type" => "submit", "value" => check_btn_val, ...}
  Submit
  %br
  #{addtnl_txt}

Works nice, i.e. %br is ignored if addtnl_txt is empty

Your case is more similar to this, so you could use string interpolation:

   - if @count < 0
      - check_btn_val = "Submit"
    - else
      - check_btn_val = "Submit<br>You have $#{@count} submissions remaining".html_safe
    %input{"type" => "submit", "value" => check_btn_val, ...}
