# Requirements - Swatchline 1.x documentation

> The WordPress, WooCommerce and PHP versions Swatchline needs, and the themes and products it works with.

## Versions

| | Minimum |
|---|---|
| WordPress | 6.5 |
| WooCommerce | 8.2 (tested up to 11.1) |
| PHP | 7.4 |

## Themes and blocks

Swatchline puts its swatches where WooCommerce draws the attribute dropdowns of a variable product, so it works with:

- **Classic themes** such as Storefront, which use WooCommerce's product templates.
- **Block themes** such as Twenty Twenty-Five: the single product template's **Add to Cart Form** block, and the **Add to Cart + Options** block (see **Block themes**).

The swatches take your theme's text colour and font.

## Products

**Variable products**: each attribute used for variations whose swatch type isn't Dropdown shows swatches. Attributes added under **Products → Attributes** (global attributes) get Colour, Image or Label swatches; attributes typed on a single product (custom attributes) can show as Label swatches, see **Settings**.

Simple, grouped and external products have no variations to choose, so nothing changes for them.

## Other plugins

Swatchline keeps WooCommerce's own dropdowns in the form, hidden, and sets them when a customer picks a swatch. Plugins that work with the variation form (price displays, product add-ons, stock messages, quick views) keep working with it.
