# How to Add Dropdown, Multiselect, and Radio Fields

To let customers choose from a set list at checkout, use the Select, Multiselect, or Radio field type in [Custom Checkout Fields for WooCommerce](https://wpfactory.com/item/custom-checkout-fields-for-woocommerce/). All three share one options group, including an optional Select2 enhanced dropdown.

### Set the type and options

1. Go to **WPFactory > Custom Checkout Fields** (also reachable at **WooCommerce > Settings > Custom Checkout Fields**).
2. Open a field tab and set **Type** to **Select**, **Multiselect**, or **Radio**.
3. Scroll to **Select/Multiselect/Radio Type Options** and enter your choices in **Options**, one per line.

### Options reference

| Label | Option ID | Default |
| --- | --- | --- |
| Options (one per line) | `alg_wc_ccf_type_select_options_1` | Empty |
| Select/multiselect: "Select2" | `alg_wc_ccf_type_select_select2_1` | No |
| Select2: Min input | `alg_wc_ccf_type_select_select2_min_input_1` | 0 |
| Select2: Max input | `alg_wc_ccf_type_select_select2_max_input_1` | 0 |
| Select2: Text input by user | `alg_wc_ccf_type_select_select2_is_tagging_1` | No |
| Select2: Custom text | `alg_wc_ccf_type_select_select2_is_i18n_1` | No |

### How the three types differ

- **Select** is a single-choice dropdown. If you set a Placeholder, it becomes the empty first option.
- **Multiselect** lets the customer pick several values, which are saved as a list. Prepopulate and User profile do not apply to Multiselect.
- **Radio** shows all choices as radio buttons, so every option is visible at once.

### Using Select2

Enable **Select2** to turn a Select or Multiselect into a searchable dropdown. Then, if you want:

- **Min input** and **Max input** set how many characters trigger and cap the search box (0 ignores the limit).
- **Text input by user** (tagging) lets customers add their own value that is not in your list.
- **Custom text** reveals text fields to translate the Select2 messages, such as "No matches found" and "Searching".

### Get more fields
