[OPTIS Product Options, Variant](/product-options) 2. [20 Option Types](/product-options/20-option-types) 3. [Text Input](/product-options/20-option-types/text-input) # Text box A **Text box** is a single-line field for short text - unlike a [Text area](/product-options/20-option-types/text-input/text-area), it holds one line only, so it's best for short answers. ![](https://storage.crisp.chat/users/helpdesk/website/-/6/c/9/c/6c9c89cbb9046800/d5444597-c434-4538-9645-ccf012_towqyn.png) ## When to use a Text box * **Personalization** - a name or short message to engrave or print. * **Forms** - a shipping address, a note, or another short detail. * **Order notes** - a comment or special request for the order. ## How to add a Text box option ### Step 1: Add the option Open **1. Add options**, click **Add option**, tick **Text box** under **Text input** on the **New options** tab, then click **Add options**. ![](https://storage.crisp.chat/users/helpdesk/website/-/f/2/5/7/f257064883dab000/d8203f5d-bf8c-4c72-bd8e-d5cab6_1ech9sj.png) ![](https://storage.crisp.chat/users/helpdesk/website/-/a/0/d/b/a0dbdf0a8beb0800/82605b80-9194-4f21-8329-361a31_zeq8tr.png) ### Step 2: Name it Enter the **Label on product** (e.g., "Input your name", "Note"). Use **Label on cart** if the cart and order should show a different name. Tick any options below based on your needs: * **Required field** if customers must fill it in * **Hide option label** to hide the label ![](https://storage.crisp.chat/users/helpdesk/website/-/1/3/e/6/13e60bb80801c200/e84a1214-7ed4-4b1a-922a-ecdc07_1kxrl52.png) ### Step 3: Save and test Click **Save**, then open the product page on your store to check that the Text box works correctly. ![](https://storage.crisp.chat/users/helpdesk/website/-/b/6/3/2/b6328528a627b000/5b3047af-370c-4480-ab0d-f64c84_ytawcj.png) ## Option settings Set only what you need - all of the settings below are optional. ![](https://storage.crisp.chat/users/helpdesk/website/-/9/1/3/1/9131838ee9778000/c463e1eb-a50a-4dc8-be71-466450_4lppbr.png) * **SKU** - a SKU for this field.
