If you want to manually edit the SLD for the selected Layer then click on the Advanced tab.
| Info |
|---|
From iShare 6.0 which uses MapServer 7.6.3 the handling of Multiple Rules in an SLD that match a given style have changed from matching just the first, to applying all that match, in order of the rules. See Using Multiple Rules below for details. |
| Note |
|---|
If you manually edit the SLD via the Advanced tab and you add entries that cannot be handled by the SLD Style Editor then the Advanced tab will be your only option. |
...
Use a WHERE clause in the SQL statement for your Layer to limit the features being displayed rather than using FILTER statements in the SLD styling. Only use FILTER statements to style the display of the visible features.

Using Multiple Rules
If you wish to apply different styles to a Layer then you can do this using Multiple Rules.
| Note |
|---|
|
From iShare 6.0, due to the change in the way that Multiple Rules are handled i.e. Rules now apply to all that match not just the first match it finds, the solution is to use the <ElseFilter/> in the Rule which is used to match all not-otherwise-matched features. This goes in the Rule in the place that a Filter would normally occupy, e.g. in this simplified SLD, there’s a Rule with a Filter to match features with a crime_type value of Vehicle crime and a second Rule that uses ElseFilter to apply to all other features. Without the ElseFilter, every feature would have a fill colour of #FF8000. | Code Block |
