Activity toolbox
This guide is will help you navigate the activity creation toolbox and its elements.
Adding and rearranging elements
New activity elements can be added when selecting the button Add Question that is situated right in the middle of the activity designer window. Select the most suitable question type from the pop-up window that will appear. Once these elements are in the activity designer area, they can be modified, edited, and reordered to suit the needs of the specific activity.
When hovering over each each question, a toolbar appears at the bottom of the question, allowing you to make the necessary changes and access the element Settings.

For example, re-ordering the activity elements can be easily done by dragging the hamburger glyph (two horizontal lines of dots) in the top-middle part of each element.
Available activity elements
The below activity elements are currently available.
Radiogroup allows asking multiple-choice questions or items from the respondent. Only one item may be selected from this list.
Checkbox also allows asking multiple-choice questions or items from the respondent. However, multiple items can be checked and only those checked are recorded as the response.
The Rating activity element asks a respondent to choose a number across the range presented. Only one value may be selected.
A respondent is presented with a drop-down list of items. Only one of these items can be selected, and only the selected item will be recorded as the response.
This question type can be useful when the respondent is presented with an extensive list of choices, e.g., cities, countries, regions.
The Boolean activity element presents a respondent with a yes or no answer. The respondent's response will be recorded in the survey as true (yes) or false (no).
The File activity element allows the respondent to upload one or multiple files as their response. Furthermore, the number of File elements per one activity is unlimited. The files uploaded by the respondents can be reviewed when opening each participants response in the Activity participants list.
Several additional options for the File question type can be enabled in Settings.

Some of them are allowing multiple files to be uploaded, enabling image preview, specifying the allowed file formats, maximum file size, image height and width, creating logic and others.
Single Input
Single Input allows to ask a simple question or request a non-predetermined input from the respondent. A single line is presented to the respondent and there are no limits on the possible input so the respondent may enter any text and any amount of text determined by validation rules selected.
The Comment activity element asks for a non-predetermined input from a respondent. A text box is presented to the respondent. There are no limits on the possible input so the respondent may enter any text and any amount of text.
Multiple Text
The Multiple Text activity element allows for a respondent to input multiple Single line inputs. See Single Input above for a basic description. Multiple Text presents a stacked series of Single Input entries.
Matrix (single choice)
It allows for an array of radio buttons to be presented in rows and columns. The number of rows and columns can be adjusted, however, only one item per row can be selected. Names of rows and columns can be edited in the Activity element settings. The order that rows are presented to the respondent can be set to random or initial (the latter will sort rows alphabetically by the first letter).
Matrix (multiple choice)
This element presents the respondent with an array of columns and rows. Each cell of the array can be configured with a list of selectable items. These selectable items can be presented to the respondent through the following cell types:
Dropdown, Checkbox, Radiogroup, Single Input, Comment, Boolean, Expression, Rating. The number of columns and rows, the titles of rows, and the value of the selectable items can also be edited via Activity element settings.
Matrix (dynamic rows)
Dynamic Row Matrix contains the same functionality as the Matrix (Multiple Choice) element but adds a dynamic element that is controlled by the respondent. Respondents can add or remove rows according to their needs.
The HTML element enables HTML to be added to the activity, allowing diverse formatting of text (see example below), adding paragraphs, and the inclusion of links, images, and other media content.
Expression (read-only)
The Expression element allows to display read-only information to the respondents with help of various functions that this element supports, such as iif(), age(), min(), max(), count(), avg() among others.
