Nunjucks macro options

Use options to customise the appearance, content and behaviour of a component when using a macro, for example, changing the text.

Some options are required for the macro to work; these are marked as "Required" in the option description.

If you're using Nunjucks macros in production with "html" options, or ones ending with "html", you must sanitise the HTML to protect against cross-site scripting exploits.

When to use text input

Use text input when you need users to enter text that’s no longer than a single line, such as their name or phone number.

When not to use text input

Do not use text input if you need users to enter longer answers that might span several lines. In this case, use textarea.

How to use text input

Label text inputs

Give text input a visible label.

Do not use placeholder text for a label as it vanishes when users click on the text input.

Align labels above the text inputs they refer to. Labels should be short, direct and written in sentence case. Do not use colons at the end of labels.

Make text inputs the right size

Help users understand what they should enter by making text inputs the right size for the information you want them to give you.

By default, the width of text inputs is fluid and will fit the full width of the container they are placed into.

If you want to make the input smaller, you can either use a fixed width input, or use the width override classes to create a smaller, fluid width input.

Fixed width inputs

Use fixed width inputs for content that has a specific, known length. For example, postcode inputs should be postcode-sized and phone number inputs should be phone number-sized.

On fixed width inputs, the width will remain fixed on all screens unless it is wider than the viewport, in which case it will shrink to fit.

If you’re asking the user to enter a whole number and you want to bring up the numeric keypad on a mobile device, set the inputmode attribute to numeric and the pattern attribute to [0-9]*. See how to do this in the HTML and Nunjucks tabs in the following example.

Nunjucks macro options

Use options to customise the appearance, content and behaviour of a component when using a macro, for example, changing the text.

Some options are required for the macro to work; these are marked as "Required" in the option description.

If you're using Nunjucks macros in production with "html" options, or ones ending with "html", you must sanitise the HTML to protect against cross-site scripting exploits.
