Dropdown
The Dropdown component can be used to collect user input from a list of options. This document goes through all the properties related to the Dropdown component.
To get the configuration of legacy Dropdown component, please refer to this document.
Data
Property | Description | Expected Value |
|---|---|---|
| Label | Text to display as the label for the field. | String (e.g., Country). |
| Placeholder | A hint displayed to guide the user on what to enter. | String (e.g., Choose an option). |
Options
Allows you to add options to the dropdown field. You can click on Add new option and add options manually or enable Dynamic options and enter the options using code.
Example Code for Dynamic Columns
- Passing an array of objects and specifying each value:
{{
[{label: 'option1', value: 1, disable: false, visible: true, default: true},
{label: 'option2', value: 2, disable: false, visible: true},
{label: 'option3', value: 3, disable: false, visible: true}]
}}
- Passing an array of objects with a default value from a Table component's selected row:
{{
queries.getEmployees.data.map(option => ({
label: option.firstname,
value: option.firstname,
disable: false,
visible: true,
default: option.firstname === components.table1.selectedRow.firstname
}))
}}
Options loading state
Allows you to add a loading state to the dynamically generated options. You can enable or disable the toggle button or dynamically configure the value by clicking on fx and entering a logical expression.
Events
On select
Triggers when an option is selected.
On search text changed
Triggers when search text changes.
On focus
Triggers whenever the user clicks inside the component.
On blur
Triggers whenever the user clicks outside the component.
Component specific actions (CSA)
Following actions of the component can be controlled using the component specific actions(CSA):
Actions | Description | How To Access |
|---|---|---|
| clear() | Clears the selected option. | Employ a RunJS query (for e.g., await components.dropdown1.clear()) or trigger it using an event. |
| setVisibility() | Sets the visibility of the component. | Employ a RunJS query (for e.g., await components.dropdown1.setVisibility(false)) or trigger it using an event. |
| setLoading() | Sets the loading state of the component. | Employ a RunJS query (for e.g., await components.dropdown1.setLoading(true)) or trigger it using an event. |
| setDisable() | Disables the component. | Employ a RunJS query (for e.g., await components.dropdown1.setDisable(true)) or trigger it using an event. |
| selectOption() | Selects an option. | Employ a RunJS query (for e.g., await components.dropdown1.selectOption(2)) or trigger it using an event. |
Note: The data type passed to CSAs like selectOption() depends on how you configure the component. When adding options manually using the Add new option button, values must be strings (for example, components.dropdown1.selectOption(['2'])). When using dynamic options, supply values with the correct data types as they appear in your code logic.
For example, if the code is:
{{
[
{ label: 'option1', value: 1, disable: false, visible: true, default: true },
{ label: 'option2', value: 2, disable: false, visible: true },
{ label: 'option3', value: 3, disable: false, visible: true }
]
}}
You should pass numeric values in the selectOptions component-specific action since the value type is Number:
components.dropdown1.selectOption([2])
