Plus Squared Icon

Q: When should I use it instead of a similar icon?

Use it for a hover handle at the left of each paragraph that inserts a new block below; and closed branches in a file or settings tree, drawn as a boxed expander that opens on press. For starting a new chat or a new comment thread, use the Message Add icon. For another row in a dynamic form of emails or guests, use the Plus Circle icon. For placing a new widget on a dashboard grid, use the Layout Add icon.

Plus Squared icon FAQ

What does this icon show?

Plus sign inside a rounded square, for adding blocks, creating items and expanding a collapsed row. Typical uses: insert a block in a content editor, add a new item inside a card and expand a collapsed tree row.

When should I use it instead of a similar icon?

Use it for:

A hover handle at the left of each paragraph that inserts a new block below
Closed branches in a file or settings tree, drawn as a boxed expander that opens on press

For starting a new chat or a new comment thread, use the Message Add icon. For another row in a dynamic form of emails or guests, use the Plus Circle icon. For placing a new widget on a dashboard grid, use the Layout Add icon.

Which styles does it come in?

4 styles: Outline, Solid, Duotone and Filled. Every style is drawn on the same 24 by 24 grid and installs as its own file, so you can switch styles without touching the layout.

How do I install it with the shadcn CLI?

Copy the install command from the panel above, in the style you want, and run it in your project. The shadcn CLI adds the icon as a React component that you import and render like any other. It draws in the current text color, so your text color and size classes style it. Icon installs need a ReUI Ultimate license.

What icons go well with it?

Drag and Trash sit beside it in the same toolbar or menu. More from the same family and the Actions set: Check Squared, Minus Squared, Arrow Down Wide Narrow and Arrow Up Wide Narrow.

When was it added?

It joined the ReUI icon library on June 30, 2026.
