Introduction
Calculate and manage list data directly within your Bubble app. Real-time list sum, difference, and cumulative calculations for seamless data processing. Lists Plugin enhances user experience by enabling dynamic and structured list computations within your application.
Use the Lists element to generate and compute list data effortlessly. The plugin actions and states return essential information such as the current list calculations, allowing for real-time updates and changes.
The plugin also provides states that reflect the current list calculations and content, ensuring users can always manage and utilize structured data efficiently. Implement workflows based on list data conditions, improving app functionality and user engagement by responding to data-driven events.
Plugin Actions
Arithmetic [list & list] - Perform operations between 2 lists.
Fields:
Title | Description | Type |
List of numbers 1 | The initial list for arithmetic operations. | list of numbers |
List of numbers 2 | The secondary list for arithmetic operations. | list of numbers |
Operation | This dropdown defines all allowed operations. Available operatations: addition, subtraction, multiplication, division, exponentiation, quotient of division, remainder of division, minimum, maximum, average. | Dropdown |
Replace "empty" values with 0 or 1 | Enables replacing the 'empty' values with neutral values [0 (zero) or 1 (one)]. For example, 'addition' will replace the 'empty' values with 0, and 'multiplication' - 1.
Check here how this field may affect the result. | Checkbox |
Returned values:
☝️
Bubble doesn't allow returning a list that may contain empty values. That's why the 'result' state is returned as concatenated values separated by a comma (,). This needs to be converted from text into a list of numbers. To do this, use the "result" state with the following Bubble expression: ":split by (,):each item:converted to a number" when using the state.
👉
The list length that results from the calculations will always be the same as the length of the “List of numbers 1”!
Title | Description | Type |
result | The "result" state is returned as the concatenated values separated by a comma (,). This needs to be converted from text to a list of numbers. So, use the "result" state with the following Bubble expression: ":split by (,):each item:converted to a number" while using the state.

Workflow example
How to use Arithmetic [lists] action
Compared to the 'Arithmetic [list & list]' action, which receives lists of numbers, the 'Arithmetic [lists]' action accepts multiple lists in the 'Concatenated Lists' field, but these lists must be converted to text.
- Here is a Group element that contains the used list items for calculation.
- Inside, there is a Text element that will display all the used lists.
The database contains the following values…
- The result of the calculation is stored in a custom state of the Group element and is displayed in another Text element.
- When the “Calculate Sum” button is clicked, the “Arithmetic [lists]” action is triggered with the following settings.
- All lists from 'Concatenated Lists' are converted to text using the 'join with' action.
- For the 'join with' action, a comma (
,) is used to separate each item in the list. - A comma is also used in the 'List Item Separator' field to indicate that each item in the list is separated by a comma.
- Each list is separated by an ampersand (
&). - An ampersand is also used in the 'List Separator' field to indicate that each list is separated by an ampersand.
- The 'Replace "empty" values with 0 or 1' field is enabled. This means that 'empty' values from the lists will be replaced with '0'. Check the replacement rules here.
- The lists’ length are different
- The 1st list has 2 elements.
- The 2nd list has 3 elements.
- The 3rd list has 4 elements.
- Thus, the length of the result will be 4. Check this note.
☝️
Ensure the following:
- In the preview, all lists will be concatenated, and the result will be displayed correctly.
How the ‘Replace “empty” values …’ option may affect the result
Sometimes the data stored in the database may contain 'empty' values. Theoretically, if 'empty' means 'nothing', then calculations with 'nothing' should return 'nothing'. The 'Replace “empty” values …' field indicates how the action should handle this.
- Here is a Group element that contains the used list items for calculation.
- Inside, there is a Text element that will display all the used lists.
The database contains the following values…
- The result of the calculation is stored in a custom state of the Group element and is displayed in another Text element.
- When the “Subtract” button is clicked, the “Arithmetic [list & list]” action is triggered with the following settings. The ‘Replace “empty” values …’ field is disabled!
- In the preview, the result will contain 'empty' values because the initial lists contain 'empty' values.
☝️
In a calculation with the 'Replace “empty” values ...' field disabled, if at least one of the two values is 'empty', then the result will be an 'empty' value.
- When the “Subtract” button is clicked, the “Arithmetic [list & list]” action is triggered with the following settings. The ‘Replace “empty” values …’ field is enabled!
- In the preview, the result will not contain 'empty' values because all 'empty' values are replaced before the calculation. Check the replacement rules here.
- Compare the both results.
How to use the ‘result’ state
The obtained result may be used in other elements on the page.
☝️
Bubble doesn't allow returning a list that may contain empty values. That's why the 'result' state is returned as concatenated values separated by a comma (,). This needs to be converted from text into a list of numbers. To do this, use the "result" state with the following Bubble expression: ":split by (,):each item:converted to a number" when using the state.
