|
* droplets are small codeblocks that are called from anywhere in the template.
|
|
19
|
* To call a droplet just use [[dropletname]]. optional parameters for a droplet can be used like [[dropletname?parameter=value¶meter2=value]]\
|
|
20
|
*
|
|
21
|
* 1.0.2, bugfix, Reused the evalDroplet function so the extracted parameters will be only available within the scope of the eval and cleared when ready.
|
|
22
|
* 1.0.3, optimize, reduce memory consumption, increase speed, remove CSS, enable nested droplets
|
