You can now use the `$tempvar.value` syntax when defining template variables for your dashboard widgets in Datadog, giving you more control over what tags your template variables point to and allowing you to visualize all of the data you need across any tags. This new dynamic syntax enables you to select multiple sets of tag values using a single key, unify data from different tagging conventions, simplify network traffic queries, and more. You can use this syntax to reduce the number of template variables needed by attributing values as partial strings, such as specifying a service to graph metrics from in a staging environment. Additionally, you can create "OR" statements in your graph queries using the `$tempvar.value` syntax to include both metric data tagged with different keys, and leverage this feature to build more flexible network traffic queries. With the new dynamic template variable syntax, you can easily create adaptive template variables, reducing the number of templates needed to manage and helping ensure no gaps in the data your dashboards visualize.
