Tag Properties¶
The properties that a tag contains depend on the type of tag that the user creates and the configuration that the user enables.
On the Add page, only the Basic Information and Valus configurations are displayed by default. All other configurations are not enabled. Only when the corresponding configuration is enabled, the corresponding configuration information will be displayed on the Add page in the following figure.
