Sub list with multiple items - List Control/Field

  • Updated

List control is used to display a set of data in a standard table grid with column headers. Users can enter a list of associated fields by adding rows. 

List control(or saying Field List) appears on a form as a table that contains column/field headers. These field headers can be fully customized by editing its properties. 

Tips A field list is only applicable in form builder. It reflects a string of JSON object. 

Use Design

Yeeflow offers two controls for displaying table data sets: Field List and Content List . While they satisfy similar use cases, choosing the correct control to use in your design will be dependent on the type of data you need to display. 

Use Field List when:

  • You want to consume as a grid table that structured rows and columns;
  • Users can enter the column values by adding a new row item; 
  • It's a data bound control on the form and you can custom the appearance and behavior by editing its associated fields.
  • It offers certain fields with summary expression that can be bound with other controls on the form. 

Use Content List when:

  • A flexible layout to view each row(item) rather than collecting information in a grid table;
  • Users may enter the values by adding a new page item;
  • It's unbound control on the form and you need have a associated data list to be displayed. 
  • Content displayed may vary by filter conditions (between the form and data list).

Settings of Columns(Fields)

You need add one or multiple certain fields/controls as its column header(s). Yeeflow provides the summary function that is used to produce result summaries of the results of various fields(columns). 

  • Columns Settings

Most of Yeeflow built-in controls can be used in List control also. It allows a number of certain fields to be added from "Column-Settings".

You can custom every field/column by editing its setting properties, e.g. basic settings, appearance and validations. You may also queue them by order number. 

Please note: You can hide some of the columns in this list if it's not checked. The dynamic display rule to hide this field will only hide the values of this column. 


  • Summary Settings

 The Summary Editor offers two types of summaries function:

  1. Concat  - Applicable for all types except numeric
  2. Numeric Summaries (Sum&Average&Min&Max)

You may enable "Display" these numeric column summaries under this list.


It's optional to bind the summaries result into another same control on this main form. E.g. a numeric column of this list should be bound to a numeric control of this form.

Settings of Rows(Items)

When the field list is NOT Readonly, there is a Yeeflow default that allows user to add or delete items. Oppositely a Readonly list is not allowed to configure the settings or items, which is always used to task form pages. 

  • Add Item - it allows user to add one or multiple rows based on columns.
  • Delete Item - It allows user to delete existing row(s) of this list.


  • Allow Import - Yeeflow allows user to upload file in xlsx format to a field list. 

When "Allow import" is enabled, the users have options to add item one by one, or bulk import to add a number of rows. 

Please note: To process bulk import, Each column header of your list should be unique, accordingly the upload file should have the same header name at the first row.
