Field types

Xplain reads each field's own settings, so its notes are about your field — the options you defined, the columns you named, the entry types you allowed.

Field type	What Xplain reads	The Twig	Leading advice
Plain Text	multi-line, code, character limit	{{ entry.x }}, \|nl2br when multi-line	Twig escapes it; leave \|raw off
Email, URL	—	an <a> with mailto: or href	—
Link	allowed link types	{{ entry.x.link }}, .url, .label	.element for entry links
Number, Range	decimals, min/max, prefix/suffix	\|number	zero is falsy: is not null
Money	currency, min/max	\|money	.amount is in minor units
Lightswitch	default	{% if entry.x %}	plain boolean, no .value
Date, Time	date/time/time zone	\|date(…) with a <time> element	stored UTC, shown in site time
Color	—	.hex, .rgb, .hsl	.luma for text contrast
Country	—	.name, .countryCode	localised name
Icon	—	the icon name	Craft stores the name only
JSON	—	keys straight off the value	already decoded
Dropdown, Radio Buttons, Button Group	option values	{{ entry.x }}, == 'value', .label	compare the value, not the label
Checkboxes, Multi-select	option values	.contains('value'), loop for labels	.options has every option
Table	column handles	a <table> loop by column handle	rows are arrays keyed by handle
Addresses	—	\|address	formatted for the address's country
Entries, Categories, Tags, Users, Assets	max relations, sources, file kinds, hierarchy, per-site relations	.one() or .all() by limit	eager-load it
Matrix	entry types and their fields	a full {% switch block.type.handle %}	eager-load it, nested relations too
Content Block	its inner fields	its fields straight off the value	nothing to loop or eager-load
CKEditor, Redactor	—	{{ entry.x }}	already HTML, no \|raw
anything else	the value type Craft declares	{{ entry.x }} or a loop for queries	{{ dump(…) }} in devMode

Every field also gets its translation method, whether it is searchable, whether it is required or conditional in the layout, and where it is used.
