]" ... />
Shows or hides an element based on the provided conditions.
If an element's conditions are unmet the element will be hidden and its available
property will become false
. If hidden, its value will not be part of requestData
.
Conditions can be provided as an array
, where each item has to be either an array
or a function
. The element will only become available
if all the conditions are fulfilled.
If a condition is provided as an array
, the first value must be the path
of an other field which value should be watched. The second is an operator that defines the type of comparison. The third is the expected value of the other field.
<ButtonElement name="field" :conditions="[['other_field', '==', 'expected_value']]" ... />
Hint: In case you want to check for equality you might leave the operator and pass the expected value as the second param:
<ButtonElement name="field" :conditions="[['other_field', 'expected_value']]" ... />
Available operators:
==
- expect equality!=
- expect inequality>
- expect the other element's value(s) to be higher>=
- expect the other element's value(s) to be higher or equal<
- expect the other element's value(s) to be lower<=
- expect the other element's value(s) to be lower or equal^
- expect the other element's value to start with$
- expect the other element's value to end with*
- expect the other element's value to containin
- expect to be among an array of valuesnot_in
- expect not to be among an array of valuestoday
- expect to be todaybefore
- expect to be before a date (value can be aYYYY-MM-DD
date string ortoday
)after
- expect to be after a date (value can be aYYYY-MM-DD
date string ortoday
)
The expected value can also be defined as an array
in which case any of its values will fulfill the condition.
Conditions can be defined with OR
relation or as function
. Learn more about conditions here.
columns
- Type:
object|string|number
- Default:
null
<ButtonElement label="Label" :columns="{ container: 12, label: 3, wrapper: 12 }" ... />
Sets the size of the container
, label
and wrapper
using the theme's grid system, where the:
container
is the wrapper DOM that contains bothlabel
andwrapper
label
contains the labelwrapper
contains the button.
container: 12
label: 3
wrapper: 12
The value of container
defines the size of the element's container. 12
will result in full width, 6
in half, 4
in third and so on.
The value of label
defines the amount of space the label should take up within the container. If the container
is 12
and label
is 6
the label is going to take up half the space and the button will the other half (which is calculated automatically). If the container
is 6
and label
is 6
, the label will only take up one forth and the button the rest. In case the label
has full width (12
) the button will also take up full space instead of becoming zero.
The value of wrapper
defines the size of the button wrapper within the space left for it in the container after subtracting the size of the label. If the container
is 12
and label
is 4
the space left for the button is 8
. In this case if the wrapper
value is 12
it will take up the full space left for it (which is 8
) while if it is changed to 6
it will only take up half the space left for it (4
):
<ButtonElement label="Label" :columns="{ container: 12, label: 4, wrapper: 12 }" ... />
<ButtonElement label="Label" :columns="{ container: 12, label: 4, wrapper: 6 }" ... />
Note that while the size of the button wrapper changes, the size of extras like a description or error won't be limited to the wrapper's space. Instead it will take up the full space in the container left after subtracting the size of the label:
<ButtonElement
label="Label"
:columns="{ container: 12, label: 4, wrapper: 6 }"
description="Lorem ipsum dolor sit amet, consectetur adipiscing elit"
... />
You can set the value of columns
as a number
in which case the container
will receive its value without affecting the default settings of label
and wrapper
:
<ButtonElement label="Label" :columns="6" ... /> <!-- { container: 6, label: 3, wrapper: 12 } -->
You can as well define column values for different breakpoints using the theme system's breakpoints like sm
, md
, etc. as keys:
<ButtonElement label="Label" :columns="{
xs: { container: 12, label: 12, wrapper: 12 },
sm: { container: 12, label: 4, wrapper: 12 },
md: 12,
lg: { container: 12, label: 2, wrapper: 12 }
}" ... />
Default column sizes can be defined globally in
vueform.config.js
or on form level usingcolumns
.

boolean
- Default:
false
<ButtonElement :inline="true" ... />

.
