# new Field(config)
Its a Custom Web Component. Do not use the constructor directly with the new keyword. Instead, use one of the 3 following methods:
Create the Web Component and call its init method:
const myField = document.createElement("a-field").init(config)
Or use a shorthand to create one the various field types:
const myText = createTextField({
label: "I'm a text field"
})
const myTextArea = createTextareaField({
label: "I'm a long text field",
cols: 100,
rows: 10
})
const myNumber = createNumberField({
label: "I'm a number field",
value: 250,
min: 0
})
const myDate = createDateField({
label: "I'm a date field",
value: new Date()
})
// You can also use the generic constructor, but then you'll have to specify the field type in the config, like this:
const myText = createField({
type: "number", // <= Field type, which can be: text | textarea | number | date
label: "foo",
value: 123
})
Or directly declare the config inside a container component:
const myPanel = createPanel({
title: "My panel",
items: [
{
type: "text",
label: "I'm a text"
},
{
type: "number":
label: "I'm a number"
}
]
})
myPanel.render()
