The options picker component is a great tool to fill an options-type data column or let your users select an item from a table of choice. It allows your users to pick a single option from a dropdown that is filled based on the connected data source, or through a custom schema to be used in other manners.
To add the options picker to your app, you first need to wrap it within a Form component. Once that is done you can add the
options picker through
Form > Options Picker
The options picker will now be added in an empty state to your UI.
To display options in the option picker, you have a few routes to do this. Either you can let the options prefill based on the existing data or data-schema, or you can specify custom options so you can use the choice to do something else, for example, use in Automation, or transform it yourself before adding it to a table. Below is a quick table to highlight the purpose of each method.
|Schema||When you configure your data structure, you may configure an options field to have predefined, static options. Use this method, when the options are defined and unlikely to change.||Low, medium, high|
Cold, warm, hot
|Data provider||In some cases, you may want to populate your options picker with data from a field in your database, other than predefined options. So, when new data is entered in to your database, the Options picker is updated, dynamically. Use this method when the options are not predefined and likely to update.||Categories|
|Custom||The custom method allows you to define options in the design section of the Budibase builder. It also allows you to assign a value to an option. Using the custom method, you can also:|
- populate values in the form, from an API request, or custom query.
- populate options in a form without giving the user write access to your database (good for public forms)
|Thor = correct,|
Spiderman = incorrect,
Hulk = incorrect,
Iron man = incorrect
To use options straight from the table schema of your form, you need to make sure you have your wrapping form linked to a table. You can do this in the Settings Panel of the form, and picking the correct table in the
Once this is done, you can return to the Settings Panel of the
Options Picker and define your schema. For this, you only need to select the right field, or data column, in the
Field option in the Settings Panel.
You will then automatically see the options defined in the table schema reflect.
Supported Column Types
When using a schema options source, the column must be of type 'Options' with the options provided. When using a data provider, options can be populated from Text rows.
Using a data provider is very similar to using the schema from the form, but in this case, it allows you to pick options from a data source that's different to what is configured in the form.
To be able to select a data provider, you of course need to have the form wrapped inside a Data Provider.
Data Provider as the
options source in the Settings Panel.
Next, there are 3 selections to be made in the Settings Panel. The actual data provider, the label column, and the value column.
The options provider should be the wrapping Data Provider. The
Label column is what is visible to the user to select from, and the
Value column defines what is actually selected in the background. This can be an ID or an Option data-type column, for example.
Below is a quick demonstration of dynamically populating an options picker with values from your database, using a Data Provider .
To use custom options, you need to select
Custom as the options source in the Settings Panel.
Custom, a new setting will appear in the Settings Panel, namely,
Define Options. Clicking this will open up a modal where you can specify both label and value.
Add as many options as you need, and fill both the
label and the
value field. The
label field is intended as visual to your users, where the
value field is intended for usage in your application, such as storing in a data-source, or through other means.
Autocomplete is a powerful feature which allows your user to type in the options picker to find the item they're looking for. This is especially useful when you have a long list of options to choose from. To enable this, you have to click the
Autocomplete checkbox in the Settings Panel.
This will transform the dropdown to have a search field.
To use Radio buttons, all you have to do is select the
Radio Button option through the
Type setting in the Settings Panel.
This will automatically transform the UI to use radio buttons instead of a dropdown.
The image above illustrates the vertical mode of the radio buttons. You can also specify
horizontal mode in the Settings Panel.
horizontal, your UI will look more compact, like below.
There are more settings in the Settings Panel than have been discussed here. They're not complicated but might require explanation. You can find them in the reference table below.
|Field||Connected field from the parent Form element, or custom by typing in a field name.|
|Name||The name of the field, displayed next to the options picker|
|Placeholder||The text displayed on the options panel when no option has been selected|
|Default value||A pre-selected value you can define using Bindings.|
|Disabled||Disables the field from editing|
|Configure Validation||Allows you to specify validation rules|
