Description

Following #2009, I think that indeed checkboxes need some fancy new features too. So I open this PR as a draft and discussion topic.

For now, I just add colored and outline checkboxes too see what it's possible to implement.

The others options i'm thinking are:

  • icons instead of check mark.
  • animated checks (js and Transition are paving the way).
  • label text depending on checkbox state...

What do you guys think about this ?

Beside the variable name: Any chance to increase specificity without using !important? (Haven't tested myself yet!)

I tried .ui.ui and .ui.ui.ui, but still need that !important to work... 😞

It's because there is an existing !important at

.ui.toggle.checkbox input:checked ~ label:before {
    background-color: #2185D0 !important;
}

We would need to remove the !important from there too

If you check the checkbox.less there are still a few !important for toggle and slider which are causing this. This PR is a good chance to get rid of them as well 😉

Icon instead of checkmark is doable:

But it will require more tests and code than previous modifications. Should I create another PR ?

Up to you 😉 Just make sure that each PR is based on current develop (or do everything in one PR)

I have a suggestion/idea/question:
What about replacing outline by bordered?
We already have bordered icon and bordered image

https://fomantic-ui.com/elements/icon.html#bordered-colored

However, a checkbox/radio always has an "outline" or is "bordered". Your new feature does only make the outline/border more prominent/bold/colored

Opinion?

Yeah I don't know how to really name it, since I "copy" class name from another framework. And I struck to find another class name for a no bordered checkbox as well (well the border disapear when checked).

I've added the icon variation. Works well overall, except for sizes, i'm not comfortable with advanced scss yet 😞

We have the @{size}CheckboxSize variables already, you may reuse them (i didn't test 🙄 )
Also, please use em instead of px

That means, that any icon inside the label (and not supposed to be used for the "check" icon) will vanish.
If we keep this logic, this would mean to define that icon.checkbox variations do not support Icons in the label itself

Just a thought (I don't request the following):

What about using the icon font family on icon.checkbox instead, so dont have to deal with a separate i tag? That would probably also fix the sizing issues and is the same approach as the current check icon.
Infact, this approach would mean to adjust all icons selectors which would be quite a lot.
A long time back we discussed data attributes "data-icon" which would be independent of the tag and could be reused here (yes, that would be a separate PR and huge breaking change....)
