<wa-color-picker>
Color pickers allow the user to select a color.
<wa-color-picker label="Select a color"></wa-color-picker>
This component works with standard <form>
elements. Please refer to the section on
form controls to learn more about form submission and client-side
validation.
Use the value
attribute to set an initial value for the color picker.
<wa-color-picker value="#4a90e2" label="Select a color"></wa-color-picker>
Use the opacity
attribute to enable the opacity slider. When this is enabled, the value will be
displayed as HEXA, RGBA, HSLA, or HSVA based on format
.
<wa-color-picker value="#f5a623ff" opacity label="Select a color"></wa-color-picker>
Set the color picker's format with the format
attribute. Valid options include hex
,
rgb
, hsl
, and hsv
. Note that the color picker's input will accept any
parsable format (including CSS color names) regardless of this option.
To prevent users from toggling the format themselves, add the no-format-toggle
attribute.
<wa-color-picker format="hex" value="#4a90e2" label="Select a color"></wa-color-picker> <wa-color-picker format="rgb" value="rgb(80, 227, 194)" label="Select a color"></wa-color-picker> <wa-color-picker format="hsl" value="hsl(290, 87%, 47%)" label="Select a color"></wa-color-picker> <wa-color-picker format="hsv" value="hsv(55, 89%, 97%)" label="Select a color"></wa-color-picker>
Use the swatches
attribute to add convenient presets to the color picker. Any format the color
picker can parse is acceptable (including
CSS color names), but each value must be
separated by a semicolon (;
). Alternatively, you can pass an array of color values to this
property using JavaScript.
<wa-color-picker label="Select a color" swatches=" #d0021b; #f5a623; #f8e71c; #8b572a; #7ed321; #417505; #bd10e0; #9013fe; #4a90e2; #50e3c2; #b8e986; #000; #444; #888; #ccc; #fff; " ></wa-color-picker>
Use the size
attribute to change the color picker's trigger size.
<wa-color-picker size="small" label="Select a color"></wa-color-picker> <wa-color-picker size="medium" label="Select a color"></wa-color-picker> <wa-color-picker size="large" label="Select a color"></wa-color-picker>
The color picker can be rendered as disabled.
<wa-color-picker disabled label="Select a color"></wa-color-picker>
Add descriptive help text to a color picker with the help-text
attribute. For help texts that
