Input

An input is used to enter data, like text or a number.

Demo

Usage

When to use

• Entering or editing data. Inputs are used to add or change data, like text or a number.

When not to use

• Choosing from options. Don't use an input to choose from other a list of options, use a Select instead.

Variants

Variant	Usage
input	A couple of words, sentence, or number.
textarea	Several sentences

Format

Content

Label

Demo

<InputField value="Malaria Registration" label="Program name" />

• Use a label above the input to show what the input is for.

Placeholder

Demo

<InputField placeholder="Type your program name here" label="Program name" />

• Only use placeholder text to clarify what kind of content is expected.
• Placeholder text shouldn't repeat the label.
• Always use placeholder text if a label isn't used.
• Placeholder text disappears when entering content, so make sure it's not critical.

Help text

Demo

<InputField
    placeholder="Enter program name"
    label="Program name"
    helpText="Used for data entry and shown on all reports"
/>

• Use help text to tell the user about any limitations or expectations for the content.
• Help text can also be used to clarify what the input is for if it's a complex concept.

Size

Demo

<InputField value="Malaria Registration" label="Program name" dense />

• Inputs are available in two sizes, regular and dense. Regular sized inputs are useful when there's space available. Use dense sized inputs in compact, information-dense interfaces.

Width

Demo

<InputField inputWidth="100px" />
<InputField inputWidth="220px" />

Inputs width should reflect the expected content.

• If a three digit number is expected then the input should be narrow.
• If a longer sentence is expected then the input should be wider.

Options

Textarea

Demo

<TextAreaField label="Description of symptoms" />

• Use a Textarea if more than a single sentence of content is expected.
• Textarea is available as a standalone component.

Validation

• Validating the type of data entered isn't part of the components themselves.
• Read more about form handling in DHIS2.

Read-only

Demo

<InputField value="OU897234798" label="Unique ID" readOnly />

• Use a read-only input if it makes sense to show the input, but the content can't be changed.
• Read-only inputs are useful to show that a value is locked, like a unique ID.
• Offer help text for read-only inputs if it's unclear why the content can't be changed.

State: Error

Demo

<InputField
    value="Malaria Registration"
    label="Program name"
    error
    validationText="This program name is already in use"
/>

• Use an error state if there's a problem with the content of the input, or if it's required but empty.
• Don't show an error too early, give the user a chance to finish entering data.
• The error text should help the user fix the problem. Refer to the error writing guidelines for examples.

State: Disabled

Demo

<InputField value="Referrals" label="Stage name" readOnly />

However, it is recommended to add a Tooltip to explain why the input is disabled.

<Tooltip content="Stage name is automatically generated and can't be changed.">
    <InputField value="Referrals" label="Stage name" readOnly />
</Tooltip>

• Use a disabled state if the input temporarily can't be used.
• Show a Tooltip on hover or focus to explain why the input is disabled.

Data type: Text

Demo

<InputField value="Olukayode" label="First name" inputWidth="240px" />

• Text inputs are the default type.
• Use a text input for entering any kind of text content, like a mix of letters and numbers.

Data type: Number

Demo

<InputField
    value="19"
    label="Admission count"
    inputWidth="100px"
    type="number"
/>

• Use a number input for entering numbers.
• The step value should reflect the expected content. If entering a number that's always a multiple of 10, use 10 as the step value.

Data type: Password

Demo

<InputField
    value="It's a secret!"
    label="Password"
    inputWidth="320px"
    type="password"
/>

• Use a password input whenever a user is entering a password or secret value.

Data type: Date / time

Demo

<InputField
    label="Incident date and time"
    inputWidth="240px"
    type="datetime-local"
/>

• Using date/time inputs offers different interactions depending on the user's browser.

Other data types

The following data types don't change the interaction with the input, but should be used for clarity:

• Telephone (tel)
• Email (email)
• Month (month)
• Week (week)
• Search (search)
