Tailwind Indeterminate Checkbox — Select All with Tri-State
The "select all" pattern with a real mixed state: peer-indeterminate:bg-tcb05-acc fills the master box and group-has-indeterminate:opacity-100 reveals its dash. A 20-line controller syncs parent and children — and now announces "2 of 4 selected" through a polite live region.

Which parts became utilities, which stayed CSS, and why.
input:indeterminate ~ .boxbecamepeer-indeterminate:, and the two::before/::aftermask glyphs became two inline SVGs toggled bygroup-has-checked:/group-has-indeterminate:.- The script now finds its root with
data-tcb05instead of an id, so several instances can share a page. - UI upgrade from the CSS original: a live "2 of 4 selected" count, selected rows tint, and every row is 44px tall.
- UI upgrade: removed the invalid
aria-checked="mixed"on the native input — screen readers now get the mixed state from.indeterminate, as the spec intends.
Here's a working CSS demo from CodeFronts. Use it as-is or adapt to your framework. All classes are scoped under a unique prefix so the code won't collide with your existing styles. MIT licensed.
Demo: Tailwind Indeterminate Checkbox — Select All with Tri-State
Source: https://codefronts.com/components/tailwind-css-checkboxes/tailwind-indeterminate-checkbox-select-all/
The "select all" pattern with a real mixed state: peer-indeterminate:bg-tcb05-acc fills the master box and group-has-indeterminate:opacity-100 reveals its dash. A 20-line controller syncs parent and children — and now announces "2 of 4 selected" through a polite live region.

Demo: Tailwind Indeterminate Checkbox — Select All with Tri-State
Source: https://codefronts.com/components/tailwind-css-checkboxes/tailwind-indeterminate-checkbox-select-all/
The "select all" pattern with a real mixed state: peer-indeterminate:bg-tcb05-acc fills the master box and group-has-indeterminate:opacity-100 reveals its dash. A 20-line controller syncs parent and children — and now announces "2 of 4 selected" through a polite live region.

## JavaScript
```js
(() => {
document.querySelectorAll('[data-tcb05]').forEach((root) => {
if (root.dataset.wired) return;
root.dataset.wired = '1';
const master = root.querySelector('[data-master]');
const kids = [...root.querySelectorAll('[data-child]')];
const count = root.querySelector('[data-count]');
const sync = () => {
const n = kids.filter((k) => k.checked).length;
master.checked = n === kids.length;
master.indeterminate = n > 0 && n < kids.length;
count.textContent = n + ' of ' + kids.length + ' selected';
};

sync();
});
kids.forEach((k) => k.addEventListener('change', sync));

})();
```How this works
Indeterminate is a property, not an attribute. HTML can't declare it; the script sets master.indeterminate whenever some — but not all — children are on. Tailwind's indeterminate: variant then does the painting.
Native semantics. The original also set aria-checked="mixed" on the native input, which is invalid ARIA on a checkbox that already exposes the state. It's gone: browsers report the mixed state from the property.
Count as feedback. The header's "2 of 4 selected" is written by sync() into an aria-live region.
Make it yours
- Re-theme with
--color-tcb05-acc; the dash and tick stay white. - Nested trees: run the same sync one level up for grandparent checkboxes.
- Bulk-action bar: toggle a toolbar with
group-has-[[data-child]:checked]/card:flex. - Reduce the list indent (
pl-5) on mobile.
Gotchas — read before shipping
- Clicking an indeterminate checkbox makes it checked — the controller then checks every child, matching Gmail/Drive behaviour.
- Never set
aria-checkedon a native checkbox; set.indeterminateinstead. - The script is idempotent (
data-wired), so re-running it in a playground won't double-bind.
