Angular Material - Inputs

The md-input-container, an Angular directive, is a container component that contains any <input> or <textarea> element as a child. It also supports error handling using the standard ng-messages directives and animates the messages using the ngEnter/ngLeave events or the ngShow/ngHide events.
The following table lists out the parameters and description of the different attributes of the md-input-container.
md-maxlength
The maximum number of characters allowed in this input. If this is specified, a character counter will be shown underneath the input. The purpose of the md-maxlength is to show the max length counter text. If you don't want the counter text and only need "plain" validation, you can use the "simple" ng-maxlength or maxlength attributes.
aria-label
Aria-label is required when no label is present. A warning message will be logged in the console if a label is not present.
placeholder
An alternative approach to using aria-label when the label is not present. The placeholder text is copied to the aria-label attribute.
md-no-autogrow
When present, the textareas will not grow automatically.
md-detect-hidden
When present, the textareas will be sized properly when they are revealed after being hidden. This is off by default for performance reasons because it guarantees a reflow every digest cycle.
The following example shows the use of the md-input-container directive and also the uses of inputs.
