Rails Turbo How do I render a partial when clicked?

I have a Ruby on Rails application with a popup currently set to show and hide through Turbo Toggle. However, I've noticed that this approach impacts the page loading speed.

To reduce the load times of the parent page I was thinking about rendering the tab only when clicked.

.div{ "data-controller": "toggle" } %div.{"data-action": "click->toggle#toggle touch->toggle#toggle"} = link_to 'Customers' = render "customers"

OK, let's try figure out what could be helpful for you. Basically you have three options

1. Eager-loading of frames for a better performance
2. Using Turbo-Frames for navigation
3. Using Stimulus (as you are already using it)

Either way, you have to provide a separate method and a view for rendering the customers-part - something like 'customer/:id'

For the first two options to work you have to make sure, that your customer-layout (the sub-layout) includes the turbo-frames tag. Using Rails you can do:

<%= turbo_frame_tag(@customer) do %>
  <%= #all of your customer-stuff %>
<% end %>

which renders into

 <turbo-frame id="customer_1">all of your customer-stuff</turbo-frame>

For the first option, the eager-loading of Frames is done this way:

<%= turbo_frame_tag @customer, src: customer_path(@customer) %>

For the second, it's just

<%= turbo_frame_tag @customer %>

Just make sure that you create the turbe-frame tag the same way as in your sublayout, and the replacement should happen automatically.

For the third option you could fetch the sub-page /customer/:id and replace the div for yourself. Have a look at https://stimulus.hotwired.dev/handbook/working-with-external-resources for a starting example.
