Display Fields
The Display Fields section of the toolbox holds the fields that show something rather than collect it - headings, instructions, images, links, dividers and badges. None of them take an answer from the user, so none of them save to the record, and the required and validation settings do not apply. What they do share are the label, sizing, styling and condition settings described in Common Field Settings and Field Conditions, so a heading can be shown to one group of users and hidden from another exactly like an entry field.
Most of these fields accept variables and {field} references in their text, which is what makes them useful for more than static wording: a label can greet the user by name, a link can carry the current record's number, and a barcode can print the value of a field the user just filled in.
Text Label
Plain text in a single font and style, for headings, instructions and any wording the form needs to say. Variables and {field} references are replaced when the form loads.
Default Value - The text to show. It is a multi-line box, so a paragraph or a short set of instructions can be entered directly.
Use Form Border - Draws the form's standard field border around the text, so a note lines up with the entry fields around it instead of floating.
Show All Spaces - Keeps the text exactly as typed, including runs of spaces and line breaks, instead of collapsing them the way a web page normally would. Turn it on for anything where the spacing carries meaning, such as a simple column of figures or pre-formatted text.
Math Label
Shows the result of a simple calculation. Use it for a total, a subtotal or a difference that the form should display but nobody should type.
Math Calculations - The calculation, built as a list of steps rather than typed as a formula. Each row has an Operation - add, subtract, multiply, divide or remainder - and a Field/Value, which is either another field on the form or a fixed number. The rows run in order and can be dragged to reorder them.
Decimal Places - How many decimal places the result is shown to.
Format as Currency - Shows the result with the site's currency symbol and grouping.
For anything the step list cannot express, put the expression in an ordinary field's value instead; the Calculated Fields topic covers the full syntax and the built-in functions.
Rich Text Label
Formatted text - headings, bold, lists, colors and embedded images - for wording that needs more than one style. Use it for terms and conditions, letterhead-style headers and any block that would otherwise take half a dozen Text Labels to build. Variables and {field} references are replaced when the form loads. For text the user is meant to write, use a Rich Text Entry field from the Advanced Input section instead.
Image
Shows a picture. The image has to be hosted somewhere the browser can reach it; using the ellipsis button beside the setting uploads a file into your site and creates the share needed to display it, which is the simplest route for a logo or a diagram.
Image URL - Where the image comes from. Variables can be used, so the picture can change with the record.
Match Display Size to Image - Sets the field's Height and Width to the size of the image that is currently loaded. Do this once the image is settled: it holds the space open while the picture is still downloading and stops the rest of the form jumping down the page as images arrive.
Link URL and Link target - Make the image clickable and open an address when it is clicked. The target is _self for the current tab, _blank for a new one, or a name to reuse a particular window.
The default image for a new Image field is set in the Public Access settings, so a site's own banner appears rather than a placeholder.
External Link
A clickable hyperlink out to another page.
Link URL - The address. Variables and {field} references are replaced, so a link can point at something specific to the record in front of the user.
Link Text - The wording shown. Write what the reader will get rather than the address itself.
Link target - _self, _blank or a window name, as above.
Horizontal Line
A rule across the form, for breaking a long page into readable sections. It can also be given a Link URL and Link target if the divider should double as a link, though a plain External Link is usually clearer.
Bullet List
A fixed list of points.
List Items - The lines to show. Items can be dragged into order.
List Style - Dots for a normal bulleted list, Numbers for a numbered one, List Group for boxed rows that stand out as a block, or None for plain lines with no marker.
YouTube Video
Embeds a video in the form, for instructions or a welcome message.
Video Embed URL - The video's embed address, not the address from the browser's location bar. YouTube provides it under the video's Share and Embed options.
Barcode
Draws a barcode from a value, so a printed form carries something a scanner can read.
Barcode Value - The value to encode. Variables and {field} references are replaced, which is how a barcode carries the record number or a reference the user has just entered.
Barcode Type - 3 of 9 or QR Code. Note that 3 of 9 converts letters to upper case, so a value whose case matters should use a QR Code.
Set the field's Width and Height to suit the scanner and the paper; a barcode that is too small or too narrow will not read reliably.
Progress
A progress bar whose fill reflects a value, for showing how far through a process something is.
Field Value - The value that drives the bar, usually a variable or a {field} reference.
Bar Color - The colour of the bar.
Custom Colors - Ranges that override the bar colour depending on the value. Each row has a From, a To and a colour, so a bar can run green up to a point, amber beyond it and red at the top without any conditions being set on the field.
Print Page Break
Invisible on screen, but forces a new page when the form is printed. Drop one wherever the printed copy should break rather than letting it fall where it may.
Icon Label
Shows an icon chosen from the built-in set. Because the icon is drawn as text it takes the field's font size and colour, so it scales and recolours with the rest of the form - unlike an Image, which does not.
Icon - The icon to show, chosen from the list.
Spacer
Empty space. Use it to separate fields vertically, and as an invisible placeholder to leave a column empty inside Flexible Columns or another container.
Field Spacing - How much space the field takes.
